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.
