Action Items from August Subgroup


• Status of unknown Facilities:

– Long EZ (Dobosy) will not participate

– Xpol and 2D video disdrometer networked with 5 tipping bucket raingauges will participate


– Office of Army Research multi-beam, passive remote sensing instrument (Bach) – still unknown

• Add. Facility Information:

– Complete Lidar and Radar Information from PIs (incl. safety procedures) to request waiver from FAA

• Specs complete

• NCAR safety procedures documents are done

• Need information from other agencies

• Trevino (FAA) to review

– Communications Capabilities on Aeromet Learjet:

• Learjet does not have any Satcom system or line-of-sight communication systems

• Standard VHF radios, no details yet

– Cost to upgrade Learjet from a 4 to a 8-sonde system:

• Cost estimate and statement of work was requested 22 Octobe 2001 from Aeromet

• 8-channel dropsonde system consists of two 4-channel systems, which ATD can make available for IHOP

• Requires two Aeromet operators on Dropsonde Learjet (will be included in cost estimate)

• $4,000 in material and supplies (RF power dividers, amplifiers etc.)

• Requires twice the rack space

• Flight Operations

– Aircraft tracks

All Aircraft tracks have been modified and posted for review

 Flight tracks now show horizontal as well as side views

 Produce flight tracks on FAA backgrounds for play book – maps will be provided by FAA by 5 November.

 Provide aircraft tracks and flight play book to FAA

Schedule for all planes exists

– Meeting with military representatives for MOAs (Vance and Texas border) set for 13 November 2001. Material was provided in advance.

– Smaller aircraft meeting planned 2 days prior to

November planning meeting

– Details about NRL NP4 Training for NRL P-3 Scientists is posted on IHOP web site

• Flight Operations (cont.)

– Aircraft track data and associated displays with overlays (visit FAA and see tactical display and see about getting aircraft track displays) – meeting set up for October 28

– Communication including voice to ops center

– General aircraft utilization

– Small add-ons to aircraft carrying just lidars

– How to bring up flight hours on some planes (i.e., do we need an Office of Army Research funded aircraft or a just an Office of Army Research funded instrument?)

– Dropsonde

– Are our plans realistic (in terms of number of drops)?

The OFAP approved 400 sondes (300 on dedicated dropsonde aircraft and 100 sondes for Falcon) within the scope of the $2.3 million allocation.

– Settle on an aircraft(s) for dropsondes after looking at heights, on station time, length of time at the experiment—then see if a permission letter is needed.

Lynn Rose (Aeromet) was contacted on 25 October and asked to provide a Statement of Work and a cost estimate (120 flight hours on the Learjet

36A, 6 week participation) after the Project Office received a go-ahead from NSF.

Number of sondes in the air

A 8-channel system (two 4-channel AVAPS systems) may be possible on the Aeromet Learjet depending on operator and space availability. Will be addressed in SOW and cost estimate

– Real-time data communication (impossible or easy)

Not possible from the Aeromet Learjet or Falcon

• Surface Stations

– Provide recommendations to Van Baelen regarding location of additional GPS sensors

– Carry out land-use survey, GIS data base (ABL)

– Provide S. Richardson with any additional data requirements from OK Mesonet (non-qc’ed soil moisture data and FTP access)

– ASOS – cooperation between FSL and project office

– NWS badgering for new tapes and surface obs ?

– Priority list to Cress: what ARM data streams are most important and what data are needed in real time (any additional)—(general) disseminate discussion related to

ARM involvement in IHOP to Cress, Lilligren and Voyles

• Mobile Armada

– Check cell-phone coverage in IHOP area and identify gaps

– Produce map with all paved roads (list of roads with clay?)

– Develop Plan B if Freewave system doesn’t work

– Decide on secondary Ops Center for mobile facilities

Ops Center

– Communications (with airplanes, with mobile facilities etc.; Phone recording at Ops Center)

– Determine timing of daily meetings

– Get commitments on who does forecasting and nowcasting

– Identify people by name for Project Control responsibilities

– How forecasts will work with SPC, HPC, NESDIS, etc.

Action Items (cont’d)

• Staff for all systems in the field (staffing questionnaire) – will be part of logistics questionnaire

• Strong need for interagency communication at funding level

• Ops center (cont.)

– Outside help – weather channel, Ed Szoke

– Need a forecast team planning meeting

– Determine # of people at center

• Data Streams and Archival

– Real-time access of level II for list of sites and archival of WSR 88D data and provision in real time to Ops

Center (Kelvin discussion)

– Archival of two military radars—Vance and Frederick-work on real time

– Availability of GOES rapid scan (CERA-NESDIS)

– Can we get dropsonde data on GTS

– Data questionnaire

• Get modelers more involved in experimental design

– Will any one else step up besides FSL and CAPs with planning?

– Make sure all data on modeler list gets into the models

– Make sure NESDIS filters are not on and GTS works start to finish (check ARM data etc.)

– Parallel model evaluation team for nowcast and short time forecasts (0-9 h)
