cnvgrib-1.0 - August 2003 - Original version cnvgrib-1.0.1 - October 2003 - Corrected error converting level info for "depth below land surface" from GRIB1 to GRIB2. - Removed statement that set GRIB1 local table version to "2". cnvgrib-1.0.2 - May 2004 - Changed Master Table Version Number from 1 to the current "operational" value of 2, when converting from GRIB1 to GRIB2. - Added support for Gaussian grids. - Few minor bug fixes relating to: 1) ensemble params 191 and 192 (grib1 table ver 2) 2) negative pv surface values 3) radius of earth 4) # of missing values in PDS/PDT cnvgrib-1.1.0 - January 2005 - WMO approved the JPEG2000 and PNG Data Representation Templates ( 5.40000 and 5.40010, respectively ) for operational use. The templates were assigned WMO values of 5.40 and 5.41, respectively. Changes were made to the source and to acceptable program options to recognize either template number. - Added new option "-m" to support encoding of "Missing" data values within the data field when using Data Representation Templates 5.2 (option -p2) and 5.3 (options -p31 and -p32 ). Missing value management is an alternative to encoding a bitmap when using DRTs 5.2 and 5.3. - Fixed bug passing null pointers to routines expecting a valid target. Thanks to Jaakko Hyvatti and Portland Group. - Added fix for bug that caused seg faults on some systems when generating GRIB1 messages. Thanks to Robert Shectman for this one. cnvgrib-1.1.1 - April 2005 - Corrected the scaling factor used when converting potential vorticity surface values. cnvgrib-1.1.2 - January 2006 - Added a new option "-nv" to cause vector quantities to be stored in individual GRIB messages versus being bundled together which is the default. cnvgrib-1.1.4 - May 2007 - Added a new Grid Definition Template number 204 - Corrected the sale factor for probabilities - Added more parameters - Added the Time Range indicator 51 cnvgrib-1.1.5 - Dec 2007 - Added new local parameters conversion entries - Declared the variable rmin,rmax in routine (jpcpack.f and pngpack.f) with double precision to fix for bug that caused seg fault on NAM tile files - Added a check for the length of KPDS to determine the grib is ensemble. - Added new level (Nominal top of the Atmosphere cnvgrib-1.1.6 - Jan 2008 - Added new local parameters conversion entries - Added new grid id 195 and 196 - Fixed the V-GRD By setting the LPDS(22)=-1 cnvgrib-1.1.7 - May 2008 - Add missing management value option 0 : No explicit missing values included within data values Note: Valid only with complex packing: 1. Complex packing 2. Complex packing and spatial differencing cnvgrib-1.1.8 - Aug 2008 - Added new local parameters conversion entries and table 131 - Added a new Grid Definition Template number 3.32768 (Added Rotate Lat/Lon E-grid) cnvgrib-1.1.9 - June 2009 - Update Jasper version 1.900.1, libpng-1.2.35 and zlib-1.2.3 - Allow negative scale factors and limits for Templates 4.5 and 4.9 - Fixed bug causing seg fault when using PNG 1.2.35 - Added new local parameters conversion entries - Added level 126 (Isobaric Levea) in Pascal cnvgrib-1.2.0 - Mar 2010 - Fixed bug for checking (LUGB) unit index file - Modified to increase length of seek (512) - Added Templates (Satellite Product) 4.31 - Added Templates (ICAO WAFS Product) 4.15 - Added new local parameters conversion entries - Added Time Range Indicator Average (7) cnvgrib-1.2.1 - Aug 2010 - Added new local parameters conversion entries - Added Templates 4.40,4.41,4.42,4.43 - Added a new Grid Definition Template number 3.32769 (Added Rotate Lat/Lon None E-grid) - Added Type of Ensemble forecast 4 and 192 - Corrected parameters U/V Max Wind level to use PDT 4.0 for WAFS product cnvgrib-1.2.2 - Mar 2011 - Added new local parameters conversion entries - Added an option "masterable_ver_x to change Master Table Version when converts from GRIB1 to GRIB2. - Added new option -mastertable_ver_x to allow user to change the grib master table version from 2 to 6 - Added level/layer values from 235 to 239 cnvgrib-1.2.3 - Jul 2011 - Added new local parameters conversion entries - Changed variable kprob(1) to kpds(5) in calling - routine param_g1_to_g2 cnvgrib-1.5.0 - Aug 2013 - Added new parameters conversion entries - Fixed bug to allow to use same unit file number for index file - Added new Grid Definition Template 3.4, 3.5, 3.12,3.140 - Added new Product Definition Template 4.33, 4.34, 4.53, 4.54 cnvgrib-3.0.0 - OCT 2016 - Added new parameters in conversion entries - Restore original getidx.f from version 1.2.3 and - Modified GETIDEX to allow to open range of unit file number up to 9999 - Added new Product Definition Template numbers: 4.60, 4.61 - Fixed memory leak - Fixed complex endcoding - single-value fields or almost-single-value (ie:1.000-1.001) will lead to crash or invalid data when using complex encoding. - Fixed the use of alog(real(value)+1)/alog(2) in encoding is leading to precision issues. Replaced this with an integer implementation that is completely accurate. - Code assumes masked fields have at least one point turned on. If all points are masked out, the code will crash or produce a bad grib record once in a while. These fixes are for simple coding and complex coding. cnvgrib-3.1.0 - JAN 2017 - Re-compiled with G2LIB version 3.1.0 cnvgrib-3.1.1 - July 2018 - Checked Time Range for continuous accumulated APCP after F252 when convert from grib2 to grib1 cnvgrib-3.2.0 - Sept 2020 - Added new parameters in conversion entries - Re-compiled with G2LIB version 3.2.0
