The following is a record of the changes made to the SHOUR-HRR HIWRAP VAD analysis netcdf files. The most recent changes are located at the top of the list. ----- v02r00 ----- 21 November 2019 Initial version 2 upload. ::File name change:: Changed file naming convention to refer to the data selection strategy used to compute the VAD retrievals (details regarding the various data selection strategies will be presented in an upcoming journal article, for now contact an HAR group member for details). Only the sequential single-scan VAD retrievals will be uploaded to the HAR website for now (these correspond to updated versions of the pre-version-2 VAD retrievals). If you are interested in obtaining VAD profiles computed with other data selectio strategies, please contact an HAR group member. ::Bug Fixes:: Fixed a critical bug with all files where wind retrievals were only being performed if there was no missing data in the scan. ::Variable Additions:: To allow for VAD profiles to be screened for the number of missing data points in the ingested data for each profile, the 'npoints_valid', 'npoints_total', and 'qc5' variables were added to the netcdf files. 'npoints_valid' contains the number of nonmissing data points used to compute the VAD retrieval; 'npoints_total' contains the total number of points (missing data + nonmissing data) used to compute the VAD retrieval; 'qc5' is a quality control flag with 5 possible values which indicate the ratio between 'npoints_valid' and 'npoints_total' is 100%, 90%-100%, 75%-90%, 50%-75%, and less than 50% valid. ::Variable modifications:: Changed the definition of the 'delta_azimuth' variable from being the scan-mean azimuthal distance between each observation to being the scan-maximum azimuthal distance between each observation. Changed the behavior of 'qc3' to reflect changes to 'delta_azimuth'. Now 'qc3' is set to 1 when the scan-maximum azimuthal distance is greater than 20 degrees. ----- v01r02 ----- 25 October 2018 Added additional global metadata to netcdf files (contact information and a usage note). Fixed a bug where the across-track winds ('xvel' variable) had the incorrect sign (resulting in incorrect values for the 'uvel' and 'vvel' variables). ----- v01r01 ----- 5 October 2018 First revision pushed to website. Added source files (the L1B HIWRAP data files) to global meta data. Improved quality control process by switching from a reflectivity-factor threshold to a signal-to-noise-ratio threshold. Redefined the quality control flag variable 'qc2' to indicate where winds were likely to be contaiminated by the nadir side-lobe surface return (previously qc2 had been used to apply the reflectivity-factor thresholds). Added revision numbers in addition to the file version numbers. ----- v01r00 ----- 28 September 2018 Initial release (never pushed to website). This version did not include revision numbers and, as such, was labeled only as 'v01' (revision numbers were added in v01r01). The v01r00 label has been retroactively applied to these files.
