- OPeNDAP is a framework that simplifies all aspects of scientific data networking.
- OPeNDAP provides software which makes local data accessible to remote locations regardless of local storage format.
- OPeNDAP also provides tools for transforming existing applications into OPeNDAP clients (i.e., enabling them to remotely access OPeNDAP served data).
- OPeNDAP software is freely available.
1B GES DISC
The Level 1B algorithm and software transform Level 0 counts into geolocated and calibrated antenna temperatures (Ta) and brightness temperatures (Tb).
2A GPROF GES DISC
The 2A GPROF and 2A PRPS algorithms estimate precipitation rate from single orbits brightness temperature data from passive-microwave radiometers. The algorithms also uses ancillary information about Earth’s atmosphere and surface.
1C Microwave Brightness Temperatures GES DISC
The Level 1C algorithms calculate calibrated brightness temperature values so that the brightness temperature form an individual sensor is consistent with the brightness temperature from other passive-microwave sensors. Currently, the GPM Microwave Imager (GMI) is the reference instrument for calibrating the other sensors. The 1C data product is the lowest level passive-microwave data product that most researchers are interested in examining, although some instruments have more primitive data products available from the GPM project.
