Terra Product Descriptions: MODPTHKM

Last update: February 9 2015

Data Set Short Name:
MODPTHKM

Data Set Long Name:
MODIS/Terra Observation Pointers Daily L2G Global 500m SIN Grid

Platform:
Terra

Instrument:
MODIS

Product Description:
The MODIS Near Real Time (NRT) Global Observation Pointers (MODPTHKM) files stores information about the spatial relationship between each sensor observation and output grid cell.
MODPTHKM files are used as input to higher-level products such as MODIS Surface Reflectance and Snow Cover. Geometric information for each sensor observation is stored on a geolocated grid with Level-2 geophysical parameters stored as Level-2G gridded products. The multiple observations stored in the L2G grids are examined by the Level-3 processes to extract only the most relevant observations per grid cell.
