Clim., https://doi.org/10.1175/JCLI3702.1) COD_err, None, Retrieval uncertainty of Cloud Optical Depth REF_err, micrometer, Retrieval uncertainty of Cloud effective radius. When uncertainty greater than 2 micrometer, retrieval is considered to have failed. LWP_err, g/meter^2, Retrieval uncertainty of Liuid Water Path, based on error propogation of COD_err and ref_err 1 No good retrievals for this day 21 ----------------------------------------------------------------------------- PI_CONTACT_INFO: Samuel.leblanc@nasa.gov PLATFORM: NASA P3 LOCATION: based out of Sao Tome, actual location of measurement included in file ASSOCIATED_DATA: N/A INSTRUMENT_INFO: Derived product from 4STAR zenith measurements DATA_INFO: Using the cloud property retrieval method based on spectral transmitted light measurements described by LeBlanc, Pileskie, Schmidt, and Coddington (2015), AMT, https://doi.org/10.5194/amt-8-1361-2015 ,modified to include impact of overlying aerosol layer. UNCERTAINTY: See included variables. ULOD_FLAG: -7777 ULOD_VALUE: N/A LLOD_FLAG: -8888 LLOD_VALUE: N/A DM_CONTACT_INFO: Samuel LeBlanc, samuel.leblanc@nasa.gov PROJECT_INFO: ORACLES 2017 deployment (year 2 of 3); August-September 2017; Sao Tome STIPULATIONS_ON_USE: This is a public release of the 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. OTHER_COMMENTS: N/A REVISION: R0 R0: Archival for first public release of retrieved cloud properties from 4STAR sky radiance measurements. Using renewed look-up-table created accounting for actual above cloud AOD values (same as R3 for ORACLES-2016). Data is subject to uncertainties linked to detector stability, transfer efficiency of light through fiber optic cable, and deposition on the instrument window. Filtered out in-cloud data, bad measurements, and high clouds. ----------------------------------------------------------------------------- Start_UTC,LAT,LON,COD,REF,LWP,COD_err,REF_err,LWP_err 34169,-7.968,-14.401,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000 34170,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000 34171,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000 34172,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000 34173,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000 34174,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000 34175,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000 34176,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000 34177,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000 34178,-7.968,-14.401,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000
