Version 4.5.1 of the netCDF Operators (NCO) has been released. NCO is an Open Source package that consists of a dozen standalone, command-line programs that take netCDF files as input, then operate (e.g., derive new data, average, print, hyperslab, manipulate metadata) and output the results to screen or files in text, binary, or netCDF formats.

The NCO project is coordinated by Professor Charlie Zender of the Department of Earth System Science, University of California, Irvine. More information about the project, along with binary and source downloads, are available on the SourceForge project page.

GFS 0.25° Model Output to be Added to CONDUIT

07 July 2015

National Centers for Environmental Prediction (NCEP) Global Forecast System (GFS) model output with 0.25-degree resolution will be added to the Internet Data Distribution (IDD) CONDUIT data stream on July 28, 2015.

Update: GFS 0.25-degree output is now available via the CONDUIT data stream.

NCEP began producing the GFS model output with a 0.25-degree resolution for use in weather forecasting operations in January, 2015. Unidata Program Center staff have tested the 0.25-degree GFS model output internally and have been working with operators of top-level IDD relay sites to ensure that they have the capacity to handle the increased data volume associated with this new data stream. The approximate volume of the 0.25-degree GFS model output is 20 GB per model run, four times each day. For comparison, all of the current GFS model output delivered via CONDUIT (GFS 0.5-degree, 1-degree, and 2.5-degree) total approximately 5 GB per model run, four times each day.
