Mauna Loa Irradiances are those derived using voltage intercepts (V0) determined from carefully selected periods of deployment at NOAA’s Mauna Loa Observation site. MLO V0 values are generated following the methodology outlined under the In-situ Langley Irradiance in the Data Processing Procedures.
The data is downloaded in CSV format. Each set of data has a header. The header lines begin wth the # sign, and contains a description of location and data, along with possible data issues. The nighttime data is set to -9999 and data that are not currently available or associated with instrument errors are set to -9998.
Currently only the UV-MFRSR instruments have been processed through Manua Loa.
