Abstract : A DC-3 aircraft was instrumented to take data of solar-radiated and earth-emitted energy at different levels of altitude over, below and within stratiform clouds and above earth-surface features such as water, sand, grass, forest, snow and ice. A photometric polarimeter was designed and built to measure the cloud-reflected spectral radiance and polarization. Other measurement instruments included are up- and down-reading pyranometers, infrared radiometer and spectrometer, cloud particle sampler, liquid-water-content meter, and cloud-visibility indicator. In addition, a T-11 aerial camera, modified to match its spectral response to a typical meteorological satellite camera, was calibrated and flown by a U2 aircraft to take photographs over stratiform clouds from different altitude levels. Simultaneous flights over clouds were made by the DC-3 and U2 aircrafts at times when meteorological satellite pictures were being taken. (Author)
