Abstract

Solar radiation is one of the most important quantities in research in the field of climatology, as it acts as a driving force in most of the dynamic processes of the atmosphere. Measurement of several solar radiation parameters at the Jambi Climatology Station has been carried out using a set of instruments called the automatic solar radiation station (ASRS) since 2017. In this paper, the measurement method, data quality control, and analysis of variability of the three types of solar radiation – direct radiation, diffuse radiation, and global radiation – in the period of 2018 – 2019, have been described. The results of data quality control indicate that in general, the three radiation parameters have a good spread of values. In the 2018 – 2019 period, the three parameters reached their peak at 13.00 LT and the daily average global radiation reached 4.4 ± 1.0 kWh/m2 day-1. The peak of insolation at the Jambi Climatology Station occurred in March and September, which coincided with the equinox events. The significant cloud growth in the Jambi region affects the radiation pattern that reaches the earth surface.
