Dimensions

These fields define all dimensions that can be used for HDF-EOS swath fields.

The names "GeoTrack" and "GeoXTrack" have a special meaning for this document: "Cross-Track" data fields have a hidden dimension of "GeoXTrack"; "Along-Track" data fields have a hidden dimension of "GeoTrack"; "Full Swath Data Fields have hidden dimensions of both "GeoTrack" and "GeoXTrack".

Name Value Explanation
GeoXTrack 30 Dimension across track for footprint positions. Same as number of footprints per scanline.
GeoTrack # of scan lines in swath Dimension along track for footprint positions. Same as number of scanlines in granule. (Nominally 45 for Level-2, AMSU, and AIRS/Vis low-rate engineering; 135 for AIRS/Vis and HSB high-rate quantities)
Channel 2378 Dimension of radiance array

Geolocation Fields

These fields appear for every footprint (GeoTrack * GeoXTrack times) and correspond to footprint center coordinates and "shutter" time.

Name Explanation
Latitude Footprint boresight Latitude in degrees North (-90.0 ... 90.0)
Longitude Footprint boresight Longitude in degrees East (-180.0 ... 180.0)
Time Footprint "shutter" TAI Time: floating-point elapsed seconds since Jan 1, 1993
