MODIS/Aqua Near Real Time (NRT) Observation Pointers Daily L2G Global 500m SIN Grid Day V005Entry ID: MYDPTHKM
Abstract: The MODIS/Aqua Near Real Time (NRT) Observation Pointers Daily L2G Global 500m SIN Grid Day product (MYDPTHKM) uses Level-2G (L2G) land data storage methodology developed to satisfy the diverse needs of the MODIS land product generation algorithms, to enable efficient processing and reprocessing of MODIS land products, to ... facilitate the development of terrestrial remote sensing algorithms and science using MODIS land data, and to provide users with the original sensed MODIS observations and their sub-pixel geolocation information. The L2G data storage structure stores information concerning the Level-2 (L2) observations that fall within each Level-3 (L3) grid cell over a 24-hour (GMT) period. The measured L2 geophysical parameter and the sensing geometry information are stored for each observation. The multiple observations stored in the L2G structure are examined by the L3 processes to extract only the most relevant observations falling over each grid cell. Data Set Characteristics: Area: ~10 degrees x 10 degrees latitude/longitude Size: 1200 X 1200 rows/columns File Size: ~115 MB Resolution: 500 meters Projection: Sinusoidal Processing Level: 2G Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 9

Quality Overall NRT products match to operational with some expected minor differences from use of different ancillaries and ephemeris. There aren't any data gaps or data artifacts.
