An Initial Analysis of the Data from the Polar Orbiting Geophysical (POGS) Satellite
Abstract
The POGS (Polar Orbiting Geophysical Satellite) was launched in 1990 to measure the geomagnetic field. POGS data from selected magnetically quiet days was selected, quality checked and deleted were thought to be erroneous. A time-and-position correction was applied. The resulting data was fit to a degree 13 spherical harmonic model. Evaluation of the quality of the data indicates that it is sufficient for definition of the low-degree (say, less than 8) portion of the geomagnetic field. Further correction of the data time and position may improve this quality. (Author)
