CDF UTC_time wavelength PI Jens Redemann Institution NASA Ames Research Center Instrument ISpectrometers for Sky-Scanning, Sun-Tracking Atmospheric Research (4STAR) Mission ORACLES 2017 PI_contact_info jredemann@ou.edu Platform NASA P3 Location aBased in Sao Tome. Exact aircraft latitude, longitude, altitude are included in the data records. Data_info aMeasurements represent downwelling radiances measured while sampling at Zenith from under clouds. DM_Contact_info 'Samuel LeBlanc, samuel.leblanc@nasa.gov Project_info FORACLES 2017 deployment; August-September 2017; Based out of Sao Tome. STIPULATIONS_ON_USE This is the initial public release of the 4STAR-ZENRAD ORACLES-2017 data set. We strongly recommend that you consult the PI, both for updates to the data set, and for the proper and most recent interpretation of the data for specific science use. R0_comments Final calibrations, the data is subject to uncertainties associated with detector stability, transfer efficiency of light through fiber optic cable, cloud screening, diffuse light, deposition on the front windows. Potential of higher uncertainty at wavelengths between 390 nm - 430 nm.
