5/15/2014 Seminar – Satellite-based cloud algorithms at CIMSS, Madison

Speaker: Andi Walther (University of Wisconsin)
Date: Tuesday, May 15, 2018
Time: 4:00pm
Location: SPSC W120

Seminar Abstract:

The  Algorithm Working Group (AWG) at CIMSS is responsible for the development of satellite-based cloud algorithms for NOAA missions from several current and future sensors. Examples are the 36-years long AVHRR-based cloud climatology PATMOS-x, the current Suomi NPP/JPSS retrievals and retrieval development for the future GOES-ABI. Products include among others calibrated reflectance and radiation values, cloud detection, cloud phase, cloud top height, microphysical cloud parameters and solar insulation products. The quasi-realtime product processing for MODIS, SEVIRI, GOES, NOAA series, MTSAT and JPSS enables us to support also field campaigns, as done for the Deep Convective Clouds and Chemistry Experiment (DC3).  Data are available via or on request. My talk includes project and product examples.  I will put a special focus on the new retrieval for cloud optical thickness and effective particle size, which uses lunar reflectance in the Day/Night Band of VIIRS at night. With this presentation I hope to  stimulate and discuss new cooperation possibilities for common projects of CIMSS and LASP.
