CAC Outgoing Longwave Radiation, Monthly Means and Half Month Means

| DOI: 10.5065/ZNYP-AK49

This historical dataset is recommended for ancillary use only and not as a primary research dataset. It has likely been superseded by a newer, improved dataset.


This dataset contains monthly and semimonthly means of outgoing longwave radiation derived from polar orbiting satellites passing over each earth location at least twice daily. The data from both the "morning" and "evening" passes are on a global 2.5-degree latitude/longitude grid.

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
