North American Regional Reanalysis (NARR) for Arctic Research: Dataset Warnings
- June 17 2013: 2m air temperature, 10m winds for 2007 have been replaced because they were found to be inadvertently based on the 30m level and not the 2m and 10m levels. Please replace any of those files you obtained before that date.
- Model was rerun at NCEP due to an assimilation
problem starting at Jan 2003
and we have updated our files.
If you have acquired surface level data prior to Feb 12, 2006 please retrieve the latest version as a library error caused the files to have some erroneous values.
- Extreme values in the NCEP GRIBs 12-21Z 10 Feb 2004, 0-9Z 24 Feb 2004, and 12-21Z 10 Mar 2004 for variables
3-hourly Water Condensate Flux Convergence Accumulation (wcconv) and
