MODIS/Aqua Calibrated Radiances 1km 5-Min 1B Wide Swath Subset along CloudSat V2 (MAC021S1) at GES DISCEntry ID: GES_DISC_MAC021S1_v2
Abstract: This is the wide-swath MODIS/Aqua subset along CloudSat field of view track. The goal of the wide-swath subset is to select and return MODIS data that are within +-100 km across the CloudSat track. I.e. the resultant MODIS subset swath is about 200 km cross-track. Thus, MAC021S1 cross-track width is 201 pixels for radiances. Geolocations in the original product, however, are subsampled at 5-km, ... and thus the cross-track width of the subset geolocations is 41 pixels. Along-track, all MODIS pixels from the original product are preserved.
In the standard product, the MODIS Level 1B data set contains calibrated and geolocated at-aperture radiances for 36 discrete bands located in the 0.4 to 14.4 micron region of electromagentic spectrum. These data are generated from the MODIS Level 1A scans of raw radiance and in the process converted to geophysical units of W/(m^2 um sr). In addition, the Earth Bi-directional Reflectance Distribution Function (BRDF) may be determined for the solar reflective bands (1-19, 26) through knowledge of the solar irradiance (e.g., determined from MODIS solar diffuser data, and from the target illumination geometry). Additional data are provided including quality flags, error estimates and calibration data.
Visible, shortwave infrared, and near infrared measurements are only made during the daytime, while radiances for the thermal infrared region (bands 20-25, 27-36) are measured continuously.
Temporal_Resolution: "Two day repeat observations with a repeat orbit pattern every 16 days. The locales where the ascending and descending modes are close or intersect can have two observations per day."
