As the first of the meteorological support projects, Task 4 focused on producing two practical aids for solar system designers. The need was identified for a low-cost, portable instrumentation capable of measuring solar radiation and other meteorological data at potential and actual sites of solar system installation. Specifications for such a device were compiled and then validated using instruments built by several participating countries.

The second product was a handbook on meteorological measurements and data handling for solar energy applications which was intended to familiarize solar scientists with solar radiation data requirements and measurement techniques and enhance the meteorologist's understanding of the needs of the solar community.


  • Portable instrumentation package for measuring solar radiation
  • Handbook on solar isolation measurement
