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 2018 deployment (year 3 of 3); September-October 2018; Sao Tome STIPULATIONS_ON_USE: This is a public release of the ORACLES-2018 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 and R0 for ORACLES-2017). 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 37749,16.898,-23.363,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000 37750,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000 37751,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000 37752,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000 37753,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000 37754,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000 37755,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000 37756,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000 37757,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000 37758,16.897,-23.374,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000,-9999.000
