Re: Calipso Level 2 Aerosol profile night flags
On Jan 6, 2020 Brian Getzewich (Calipso Team) responded CALIPSO is roughly a 90-minute orbit, 45 minutes in day and 45 minutes in night. For instance, if you look at the browse images below and look at the left most column the map is white for day and brown for night. The orbit tracks in the upper ...

Re: CERES modes
Fixed Azimuth Plane Scanning (FAPS) has scan lines perpendicular to the path of the satellite, while Rotating Azimuth Plane Scan (RAPS) lines are at a wide range of angles with respect to the satellite's path. An instrument operating in RAPS has increased spectral darkening of the transmissive optic...

Re: CERES modes
The NPP platform carries the FM5 instrument, which operates in the fixed azimuth scanning mode though it can operate in a rotating azimuth scanning mode. The Terra and Aqua satellites carry two CERES instruments onboard, one in Cross-Track mode and the other in Rotating Azimuth Plane Scan (RAPS) mod...

Re: CERES FOV and Footprint
The CERES Field of View (FOV) is synonymous with the term Footprint and is determined by the Point Spread Function (PSF) which is a two-dimensional, bell-shaped function that defines the CERES instrument response to the viewed radiation field. The resolution of the CERES radiometers is usually refer...
