MOPITT V6 & V7 Processing Error

MOPITT V6 & V7 Processing Error

Friday, March 24, 2017

Update:  The effected files were reprocessed and redelivered as of April 10, 2017.


Due to an error in the reported PMC (pressure modulated cell) pressure following the February 2016 calibration activity, it was necessary to reprocess and redeliver MOPITT V6 and V7 data. Since V7 data are processed with interpolated calibration for the archival product, this required reprocessing for 2015 as well. We are still evaluating the resulting errors in total column and vertical profile CO values, but so far these appear to be relatively small (< 0.5%) and should not affect most users who have already downloaded data from 2015 or 2016.
