Subject: | SGP/ARSCL/C1 - ARSCL Cloud Bases and Low-level reflectivities |
DataStreams: | sgparscl1clothC1.c1, sgparsclbnd1clothC1.c1, sgparsclcbh1clothC1.c1 |
Description: | Prior to February 4, 2000, the ARSCL data set incorporated data from the Beaufort Laser Ceilometer as one of its inputs. Because of the BLC's high spatial resolution, this data was often chosen by ARSCL as the "CloudBaseBestEstimate" for boundary layer clouds. It was subsequently determined that the BLC cloud base was biased, with the BLC reporting cloud base heights that are 122 meters too high. The bias error will be corrected when the entire ARSCL data set is reprocessed as part of release_4. (The release version number is included the the netCDF global comments). This reprocessing will also include a small correction the the MMCR near-field reflectivities. This correction is less than 1 dB except for hydrometers within 200 meters of the surface. Thanks to Roger Marchand for helping bracket this problem. |
