Solar radiation reaching the ground determined from meteorological satellite data

Abstract: The results of the application of meteorological satellite measurements of solar irradiance reflected and scattered to space to the problem of determining the total solar flux received at the ground are emphasized. The method is outlined. Results of the parameterization of atmospheric absorption, intermediate to obtaining satellite derived insolation received at the ground, are discussed. A map of the mean daily insolation received at the ground for June 1975, derived from the application of the method to the NOAA-4 satellite scanning radiometer normalized brightness measurements, is presented for the contiguous United States.

Geomagnetic Field Under the Solar Wind

Abstract: The concept of the magnetosphere grew out of early attempts to understand the cause of geomagnetic sudden impulses.

The Prediction of Fast Stream Front Arrivals at the Earth on the Basis of Solar Wind Measurements at Smaller Solar Distances

Abstract: The problems involved in the prediction of the arrival of fast solar wind streams at the earth on the basis of measurements made by space probes in the region between 03 and 1 AU are discussed It is shown that arrival time predictions accurate to within a few hours that can be made at least as long as the large scale conditions on the Sun are relatively stationary as observed near the time of solar minimum However, the latitudinal extent of the respective high speed streams is found to be important for making quantitative predictions Coronal data sufficient for locating the sources of high speed streams can improve the precision of these predictions
