Lucas and Waliser Satellite ECT Corrected Daily, Pentad and Monthly Global OLR Datasets

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 It has likely been superseded by a newer, improved dataset.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 daily, pentad and monthly OLR data in which the bias from varying satellite equatorial crossing times (ECTs) has been estimated and then removed. This was done by starting with the twice daily 2.5 degree NCEP/NOAA OLR archive for 1974 through 1999. The ECT biases caused by afternoon satellite orbital drift AND the abrupt transition from a morning satellite to an afternoon satellite were estimated separately and then these estimates were removed.

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.
