Dear Requestor,
What follows is a substantial number of questions related to requesting one or more of the NSF Lower
Atmosphere Observing Facilities (LAOF). There are four parts to the overall request form:
Part I: General Information covers basic information about the PI(s) team, project basics,
funding, and previous LAOF use.
Part II: Operational Considerations and Logistics is especially important if the request is for a
complex, international or multi-agency field campaign as it focuses on project support activities
above and beyond the LAOF support.
Part III: Data Services and Management focuses on overall project data management activities
such as the data management plan, data sources, long-term data archival and the use of the EOL
Field Catalog.
Part IV: Facility Specific Requests is a collection of forms that cover each of the NCAR/EOL
platforms available. Included are the two NSF/NCAR aircraft (C-130, GV), airborne
instrumentation (HCR, AVAPS, HSRL), the S-Pol radar, the Integrated Sounding System, and
the Integrated Surface Flux Facility. P
It is essential that you fill out the questions posed in Part I through Part III to the best of your
knowledge, while the number of forms under Part IV depends on the facilities needed for your project.
Please note that the services listed under Part II and III will require additional NSF program funds, so
their usefulness to the campaign and overall scope should be discussed with your NSF Program
Manager.
If you have further questions, please feel free to contact Brigitte Baeuerle at 303/497-2061 or
baeuerle@ucar.edu.

A “Data Analysis Center” includes an EOL data storage server, group internet access, printer, a meeting room and collaborative
work space. Staffing typically includes a System Administrator for the first 1-2 weeks to help get the computing infrastructure and the
PI group’s laptops connected to the network. A full “Project Operations Center” typically includes the computing infrastructure and
meeting rooms as above, plus a full-time project operations coordinator, a systems administrator, and a field catalog software
engineer. EOL staff will be available to lead the daily planning meetings, and ground staff will be available to help with aircraft
coordination in the case of operations in adverse weather conditions.

EOL FIELD CATALOG
Is an EOL Field Catalog2 needed to facilitate information gathering, reporting and management?
Do you need a Situational Real-Time Display Tool (e.g., Mission Coordinator Display) to
actively monitor and direct operations?
DATA MANAGEMENT PLAN, ARCHIVE AND DATA COLLECTION
Please attach the proposed data management plan from your NSF/agency proposal
Do you intend to request restricted data access? 3
What arrangements have been made for a comprehensive long-term project data archive,
including the management and distribution of data from non-EOL platforms? Do you need EOL to
provide such an archive?
2
Examples of EOL Field Catalog can be found at catalog.eol.ucar.edu
Please note that EOL policy (www.eol.ucar.edu/content/data-policy) will make all EOL data publicly available once the
data are quality controlled, typically in less than 6 months after project completion. If a PI wants to have exclusive access to
these data for the first year, s/he has to officially request such a restriction from the EOL Director (grubisic@ucar.edu) no
later than eight weeks prior to the start of an experiment. The burden will fall on the requesting PI to request the restriction
and to monitor data distribution and access to the data once the restrictions are in place.

PART IV: FACILITY SPECIFIC REQUEST FORMS
Update 15 November 2015
Page 13
PI - Project - Facility
NSF/NCAR Aircraft (C-130 and GV) and Airborne Instrumentation
Contact Information:
Dr. Pavel Romashkin (303/497-1027; pavel@ucar.edu) - Questions related to facility requests, project
management, schedules etc.
Dr. Jorgen Jensen (303/497-1028; jbj@ucar.edu) – Questions related to EOL/RAF instrumentation
Dr. John Orlando (303/497-1486; orlando@ucar.edu) – Questions related to ACOM instrumentation
In general it is recommended that contact be made with RAF prior to submitting the final request form.
Airborne Instrumentation:
Each research payload is unique and will typically consist of some combination of EOL, ACOM and
user-supplied instrumentation. The tables in this document list available airborne sensors and
measurements. Please note that different instruments require differing levels of support.
Instrumentation is therefore separated into four categories:
1) Standard Instrumentation, i.e., provided on all projects
2) Instrumentation by Request, i.e., instrumentation that can be added to the research payload
without added expense or staff in the field, and standard data processing with output is included
in the primary dataset.
3) Instrumentation by Special Request, i.e., the addition of one or more of these systems will
require added expense for expendables and additional support crew for a field deployment.
Special data processing will be required by science staff or outside participants.
4) Instrumentation under Development, i.e., instruments that are currently under development or
being modified. Adding these systems to a payload will add expenses for expendables,
additional support crew and special data processing carried out by science staff or outside
participants.
Inclusion of any “Instrumentation by Special Request” systems will have to be coordinated via
discussions with RAF, ACOM and the science support teams assigned to those systems. Please direct all
questions related to RAF instrumentation to Dr. Jorgen Jensen, and chemistry measurements to Dr. John
Orlando.
Inclusion of any “Instrumentation Under Development” will depend upon the timing of your
deployment and the projected status of the system in question.
For a more detailed description of the airborne instrumentation, see www.eol.ucar.edu/aircraftinstrumentation.
Payload Limitations:
The number of requested instruments routinely exceeds the available space on the aircraft. We
therefore ask PIs to indicate the priority of each measurement in addressing their research goals. The
rating to be used is as follows:
1) R for required
2) D for desired
3) left blank if not needed
Update 15 November 2015

PI - Project - Facility
Wing Store Configurations:
Basic information on possible wing store configurations, rack space requirements and operator status is
included in the tables. There are a total of 10 wing pod canister positions.
On the GV, there are three basic wing store configuration options:
 Configuration 1: 6 pylons (12 canisters)
 Configuration 2: 2 pylons (4 canisters)
 Configuration 3: 6 pylons (8 canisters and 2 large pods)
User-supplied Instrumentation:
Detailed information on specific systems and platform infrastructure related to mounting user-supplied
equipment can be found in the C-130 and GV Handbooks, available on the EOL web site
(www.eol.ucar.edu/about/our-organization/raf). All user-supplied equipment must meet RAF safety and
design specifications. Refer to RAF Bulletin No. 3, No. 13 (http://www.eol.ucar.edu/raf/Bulletins/)
Base-level Satcom Support:
All projects will receive a base level of SATCOM support, which will include “Chat” (IRC), a simple
data feed to the ground of approximately 100 variables and an approximately 50 Kb image transfer once
every 3-4 minutes. Additional services can be arranged through CDS. If you desire more frequent
image delivery to the aircraft or from the aircraft, access to satellite product web pages and field catalog
graphics from the aircraft or instrument control from the ground please contact us early to discuss
requirements and allow for scheduling.

APPENDIX I: RAF POSITION ON DROPPING OBJECTS, SUCH AS
DROPSONDES FROM NCAR/NSF AIRCRAFT
The Federal Air Regulations allow for dropping objects from aircraft with the following restriction
(FAR 91.5):
No pilot in command of a civil aircraft may allow any object to be dropped from that aircraft in flight
that creates a hazard to persons or property. However, this section does not prohibit the dropping of
any object if reasonable precautions are taken to avoid injury or damage to persons or property.
The International Civil Aviation Organization (ICAO) Annex 2 Rules of the Air Part 3.1.4: Dropping or
Spraying
“Nothing shall be dropped or sprayed from an aircraft in flight except under conditions prescribed by
the appropriate authority and as indicated by relevant information, advice and/or clearance from the
appropriate air traffic services unit.”
This regulation is the basis for the RAF policy on dropping objects (dropsondes). While dropping
dropsondes over the high seas is simply an air traffic separation and potential diplomatic problem,
dropping over land significantly raises the complexity of this issue and reflects upon the liabilities of the
U.S. Government, the National Science Foundation, and the National Center for Atmospheric Research.
Therefore, we will take all reasonable precautions to avoid damage to persons or property. To
accomplish this task requires that, as a minimum:
(a) The RAF pilot in command will have a final say in the release of dropsondes on any given
flight.
(b) Dropsondes shall not be dropped over congested areas, including cities, major highways, etc.
(c) Dropsondes shall not be dropped over airways or other areas of heavy air traffic, unless positive
locations of other aircraft can be identified and avoided.
(d) The RAF pilot in command shall take reasonable and appropriate precautions to identify the
locations of other aircraft and persons or property on the ground for all drops. Reasonable
precautions shall include, but may not be limited to:
i. Locating drop locations during project/mission planning sessions in order to coordinate the
release points with the FAA (or other authority) and the property owner(s) concerned.
ii. Assuring that diplomatic clearances to release instrumentation in foreign airspace are
obtained, when required.
iii. Obtaining real-time clearance from the FAA (or other appropriate controller) to separate
the drop from other known aircraft traffic.
(e) RAF pilots shall be responsible for determination of any additional precautions that are required
to avoid damage to persons or property (e.g. altitude restrictions, clearances from the Air Traffic
Control (ATC)). They are responsible for communicating extraordinary restrictions not
implicitly contained within this policy to EOL project management personnel in time for
appropriate NSF review.
Additional restrictions may also be a factor in dropsondes releases (e.g. wilderness area restrictions).
Update 15 November 2015
Page 39
PI - Project - Facility
It should be noted that EOL has successfully dropped sondes over land in projects such as MPEX and
DEEPWAVE. Prospective PI’s that intend to request the aircraft for dropping objects are responsible
for understanding the limitations and regulations that pertain to dropping objects, which will constrain
what aircraft support they can successfully request. This memo is intended to provide guidance in this
regard, but may not contain all the regulations that might apply to dropping in a specific location.
Prospective investigators are encouraged to discuss their plans for dropping objects with RAF staff well
in advance of the submission of a request for aircraft support, so that RAF staff can assist the
investigators in this area.
