SOLAR RADIATION.

Abstract

An improved national network of radiation stations in the country is essential to provide temporal and spatial representativeness. In order to ensure the accuracy and comparability of the data, the National Radiation Centre at Pune should be strengthened so that all radiation instruments used in the country can be periodically checked and calibrated and observers trained in the operation and maintenance of radiation instruments and the processing of data. It is also necessary to establish a number of selected baseline research stations with a high frequency of very precise measurements for studies of climate change, variability and long term trends. The radiation and other data collected at all the stations should be archived and published, periodically so that the information will be available to all solar energy users in the country in the form they need.
