NASA | OLYMPEX Scientists in the Field: Rachael Kroodsma

The video features an instrument scientist from the Space Flight Center discussing the COSMERE project. The scientist explains the frequency similarities between Kashmir and the GMI microwave radiometer on GPM, and how flying COSMERE on the DC-8 allows for measurement validation. The radiometer measures naturally emitted radiation from rain and snow. The scientist specializes in microwave radiometer calibration and data analysis, and shares their enthusiasm for fieldwork and understanding how instruments function together.
