Weighted Irradiance Data
MLO Langley Irradiance
MLO Irradiance is the irradiance in Watts per (square meter per nonometer) derived using an MLO calibration factor. This factor ia a value produced by applying Langley derived responsivities to the UV or visible MFRSR cosine corrected voltages. The MLO calibrations are Langley calibrations from carefully selected periods of deployment at NOAA’s Mauna Loa Observation site.

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.
