On Jan 2, 2020 Brian Getzewich (Calipso Team) responded Profile time in the Lidar Level 2 Aerosol Profile product is reported in both TAI and UTC format….the definitions are below. Profile_Time Time, expressed in International Atomic Time (TAI). Units are in seconds, starting from January 1, 1993. ...

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 ...

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...

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...

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...

Aqua has a 1:30 PM equator crossing time.
Terra has a 10:30 AM equator crossing time.
