Paper Abstract

The local Equator Crossing Times (EXT) of all NOAA platforms have been summarized as a function of time and approximated analytically. The fit equations (superposition of two harmonic terms, with platform-specific amplitudes, frequencies, and phases) accurately reconstruct all past EXTs to within ±2 min and also allow extrapolation in time. Fit equations are summarized and used to predict the future EXT evolution. This information is important for generation of meaningful environmental and stable climate data records from data of all radiometric sensors onboard NOAA platforms.
