Re: Newsletter
Here is the latest WG5 news. If you have any updates or other comments, please email me.
Steve Krueger, chair of GCSS and organizer of the "GCSS-ARM Workshop" has requested that each of the working group chairs submit a list of participants to receive an invitation to this Workshop. Steve says that the 100+ on the WG5 participant list is too many, and has asked me to give him a shorter list of names. Hence I am asking anyone that is interested in participating in this Workshop to email me by Nov 16 stating that you would like to attend, including a title and very short abstract of a poster you would like to present. I will then forward the list of interested participants to Steve Krueger.
Note: this meeting will include some plenary presentations from each of the GCSS Working Groups, poster sessions, some plenary presentations on large scale cloud modelling issues. There will also be opportunities for the individual working groups to hold meetings.
You might be interested in a web product that's now available from Jeff Key jkey@ssec.wisc.edu: near real-time polar clouds and radiation from AVHRR. Plots of suface temperature and albedo, cloud properties, and radiation are available once daily. Have a look: http://stratus.ssec.wisc.edu/projects/rtcaspr.
Caution: This is a developmental version of an experimental product!
Prof. Yasushi Fujiyoshi (fujiyo@lowtem.hokudai.ac.jp) informs us of plans to make a special observation of the Arctic stratus by using the research vessel [MIRAI] (JAMSTEC) next year. The ship will be in the Arctic sea region from end of September to middle of October, 2002. The focus of the project is onhorizontal (3D) structure of the stratus, and other mesoscale/synoptic disturbances that appeared in the Arctic sea.
The following measurements are planned:
- Upper air sounding (MIRAI)
- C-band Doppler radar (MIRAI) (range=250km)
- Ceilo-meter (MIRAI)
- Meteorological components (MIRAI) temperature, relative humidity, SW/LW radiation, wind speed/direction, etc.
- Oceanological components (MIRAI) vertical profiles of sea temperature and salinity, current, depth, etc.
- LIDAR (NIES)(with ploarization)
- 95GHz Cloud Doppler Radar (CRL)
- Wind Profiler (or sodar with RASS)
- Microwave radiometer (CRL)
- Latent and sensible heat fluxes near sea surface (MIRAI)
- Tethered Balloon up to 1000m
- Direct measurements of SW/LW radiation, air temperature/humidity, cloud droplets, ice particles
- Direct sampling of aerosol, CCN, ice nuclei, cloud water, ice water, water vapor
We will try to simulate the cloud by using the following models:
- Large Eddy Simulation (LES)
- Cloud-microphysical model
- Cloud resolving models
- NIES-CCSR GCM
