In situ calibrated UV/visible irradiance is the spectral irradiance in Watts per (square meter per nanometer) measured by a UV-MFRSR/vis-MFRSR using Langley derived calibration factors that have been calculated using clear sky data at the deployment station. The Langley method extrapolates the measured direct beam to zero air mass where the incident irradiance is equal to the extra-terrestrial value. To insure quality data, the In Situ calibrated data is available through the previous month.
Graphs of the data are available for a time selection of two months or less. Also provided, is a feature to export the data to a file on your local computer in several different formats(excel, csv, xml).Keep in mind a year's worth of data is about 25 megabytes, and will take almost 2 minutes to generate.
