March 23, 2015: changed precipitation comment for monthly files to say 'monthly' not 'daily'
July 1,2014: Daily/monthly data for specific humidity has units of kg kg-1 not '1' as in the metadata. This is now fixed to be 'kg kg-1'.
Jun 18,2014: Two files from this archive had incomplete netcdf files resulting in 0's for most of the time series. These have been replaced and are now availble for download. The 2 files are: maca_rhsmin_MRI-CGCM3_historical_1950_1959_WUSA.nc, and maca_tasmin_bcc-csm1-1-m_historical_1970_1979_WUSA.nc.
May 29,2014: Daily/monthly BNU-ESM data for precipitation is being recalled due to an error in the raw BNU-ESM data provided by this GCM. They added snow twice when computing the total precipitation rate. The MACA data for this model cannot be corrected, as it doesn't seem that BNU-ESM has plans to correct their raw GCM data. For more information, see the archive
May 5, 2014: Daily/Monthly wind data (i.e. was/uas/vas) for CCSM4 were not added to the original archive and are now unavailable. This data will will be available with MACAv2-METDATA.
May 5, 2014: Daily/Monthly rsds data for HadGEM2-ES/HadGEM2-ES365 RCP4.5 have been recalled due to an error in the years 2095-2099 in extraction from the raw data. This data will not be replaced, but will be updated with MACAv2-METDATA.
Apr 28, 2014: All previous monthly files for rsds,uas,vas have been updated with a slightly larger grid (extra row/column) so that the grid now matches the tasmax/tasmin/huss/pr/dps data. Note however that the extra row/column has missing values so this does not add data to the old data.
Mar 16,2014: Monthly data for tasmax/tasmin/huss/pr/dps for all models has been recalled and replaced with new corrected data. For more information, see the archive.
Jan 17, 2014: THREDDS URL Download script is resulting in erroneous data for the 2 HadGEM2 models which are 360-day year models. These two models have been removed from the THREDDS download script until this is fixed.
Dec 2, 2013: THREDDS URL Download script had an error whereby it wasn't retrieving the last year of data. Fixed.
Nov 10,2013: Monthly data for CCSM4 was found to have 523x442 values for tasmin,tasmax. These files should have 522x441 values and have been corrected.
Nov 4,2013: Daily data for 6 more GCMs were made available through the URL download for the MACAv1 method.
Feb 10,2013: The time variable on all previous monthly files have been update due to being leap instead of noleap times. If the time variable for each month is important to your application, please redownload monthly files with metadata dates prior to Feb 1,2013.
Dec 30,2012: All previous monthly files have been updated due to erroneous values. Please redownload monthly files with metadata dates prior to Dec 24,2012.
Dec 19,2012: All previous monthly files have been removed. New monthly files will be added as they become available. These monthly files will be daily data aggregated to monthly scales and adjusted so that they are on the PRISM 4-km grid.
Nov 26, 2012: tasmin/tasmax/rhsmin/rhsmax/huss files have been corrected. Please redownload files with metadata dates prior to October 20,2012. All files have now been uploaded
Sept 24, 2012: All tasmin files for rcp45/85 have been corrected. Please redownload tasmin 45/85 files with
metadata dates prior to September 17,2012.
