An Operational Cloud Verification System and Its Application to Validate Cloud Simulations in Operational Models
نویسندگان
چکیده
Clouds play an important role in regulating atmospheric dynamics and thermodynamics by redistributing momentum, thermal and moisture through mixing, latent heat release, and microphysical processes. However, conventional observational data for such important parameters are usually not available. An operational cloud verification system is being developed at the Joint Center for Satellite Data Assimilation, aiming towards validating the cloud simulations in the operational models and guiding further improvement of the prognostic cloud schemes. The system collects satellite-retrieved cloud products such as liquid water and ice paths (LWP/IWP), total precipitable water (TPW), surface rain rate, cloud top pressure and temperature, cloud amount and the others from Microwave Surface and Precipitation Products System (MSPPS), Advanced Television InfraRed Observation Satellite (TIROS) Operational Vertical Sounder (ATOVS), Clouds from Advanced Very High Resolution Radiometer (AVHRR) (CLAVR) from Polar Operational Environmental Satellites (POES) and Automated Surface Observing System (ASOS) from Geostationary Operational Environmental Satellites (GOES).
