This week on the CIMSS Satellite Blog: The Cooperative Institute for Meteorological Satellite Studies (CIMSS) Satellite Blog showcases compelling examples to document the utility and beauty of satellite imagery. Entries this week include: NGFS Detections of the Hughes Fire in Los Angeles County, Historic Snowstorm across the Deep South, True-Color imagery at different scales, Cold/dry arctic air mass over South Dakota (with some lake effect snow), and Blowing snow across eastern North Dakota and western Minnesota. (S. Bachmeier, S. Lindstrom, CIMSS; 608 263 4425)

Overview Paper on 2D and 3D Satellite-derived Winds Published: Atmospheric motion vectors (AMVs) have been routinely derived from global geostationary and polar orbiting satellite imagers since the 1990s and have been widely used in numerical weather prediction. These two-dimensional (2D) AMVs result from tracking clouds and moisture primarily from the infrared and visible bands. Hyperspectral infrared sounder observations from polar orbiting satellites have been used for 3D wind exploration, but lack the temporal and spatial coverage achieved by geostationary satellites. This paper provides an overview of tracking atmospheric features for winds using satellite passive remote sensing method, and the evolution from 2D to 3D with upcoming advanced hyperspectral infrared sounders onboard the geostationary orbit, as well as challenges and future perspectives.
