Abstract: A computer can be used to calculate look angles for automatic picture transmission (APT) receiving stations. This method eliminates the laborious use of the plotting board and overlays, and enables the APT operator to have ...

Abstract: An experiment was undertaken to measure the equivalent blackbody temperature of cloud tops of a severe storm. This was done to evaluate the common meteorological practice of determining cloud top altitude by equating the ...

Abstract: By automatically tracking the sun, a four-channel solar radiometer was used to continuously measure optical depth and atmospheric water vapor. The design of this autotracking solar radiometer is presented to allow construction ...
