Title: “Water Vapour in the Climate System (WaVaCS)”
1./ Individual’s Name:
Justus Notholt
2./ Organization Name & Address:
University of Bremen
Institute of Environmental Physics
PO Box 330440
28334 Bremen
Germany
3./ Contribution:
a./ Role in Action:
Mention if you are member of the action, member of MC, chair / vice-chair
I am a member of the Working group 1, working on water vapour observations
I am also a member of the NDACC steering committee.
b./ Parts of the scientific programme where contributions will be made:
Mention the Deliverables you wish to contribute from the Memorandum of Understanding
We will contribute with water vapour observations for the troposphere from FTIR and
the stratosphere from microwave ground-based observations from several stations in
Spitsbergen (FTIR + MW), Bremen (FTIR), and Paramaribo/Suriname (FTIR) and
Merida/Venezuela (MW). The stations are part of the NDACC (Network for the
Detection of Atmocpheric Composition and Change). In addition we will contribute
with microwave satellite data from AMSU for water vapour and clouds.
4./ Deliverables:
Mention the results you will share with the Action
Results from our FTIR observations for tropospheric water, results from our
microwave instruments for the stratospheric and lower mesospheric water. We can
deliver data for the sites mentioned above.
5./ Timetable:
Provide the timing of your activities with respect to the Action's timetable
Data can be delivered approximately once or twice per year.
6./ Manpower approximately dedicated to the Action:
Give the approximate manpower dedicated to the activities included in the action
2 PhD-students
7./ Assurance:
Mention the reasons why the proposed work will be done (sources of funding, availability of data /
tools, etc.)
The work is part of our regular NDACC activities, part of the national DFG project
CAWSES, and part of a planned satellite project.
8./ Foreseen collaboration:
Cooperation within the NDACC for FTIR and MW activities. Cooperation with
modelers to interpret the satellite data.
9./ Previous experience:
Individual’s Name:
Give a brief resume of your experiences relevant for the COST action
Persons involved are: Justus Notholt, Georg Heygster, Mathias Palm, Sven Golchert.
The IUP is working since many years successfully in this area.
