MDISC Data Subset

IMPORTANT MESSAGE 09-03-2009: The subsetting capabilities for MERRA data have recently been enhanced. New options include subsetting MERRA monthly data products, hourly time subset in daily products, mean averages over the time in daily products, and vertical subsetting for 3D products. If you have downloaded model level 3D data in the past through the MERRA Data Subsetter please note that the vertical array may be in a reverse order than the original data product. The data has been verified and is still accurate. In this new release functionality was put in place to output the vertical arrays in the same order as the original files. If you have any questions please contact Dana Ostrenga at Dana.Ostrenga@nasa.gov. Thank you for your patience.
