Missing Days in NARR
Missing Days in NARR
I have found a few days missing from the NARR ARL data set thus far and continue to find them in various months and years. It is a sporadic problem but appears to be linked to the NARR data set itself. For instance, try to run a back trajectory for May 30 or May 31, 2003 in the NARR data set. The online version of HYSPLIT did not even give me the option of choosing May 31st, and also did not successfully run the trajectory for May 30. Wanted to pass the info along. Thanks.

To update:
I have found 3 missing/bad days, all from 2003.

5/31/2003

My analysis only looks at data from 1980 to Sep 2014.
