NMC LFM North America Tropospheric Analyses

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 It has likely been superseded by a newer, improved dataset.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 the Limited Fine Mesh (LFM) model output from NCEP. The output contains initial time analyses and forecast fields from 6 hours out to 48 hours. These grids are no longer being produced by NCEP. The December, 1995 data is the last data we will archive from the LFM model.

Data License:
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.
