NCAR's Computational and Information Systems Laboratory invites NSF-supported university researchers in the atmospheric, oceanic, and related sciences to submit large allocation requests for the Yellowstone High Performance Computing system by September 15, 2014.
For the Yellowstone system, computational requests greater than 200,000 core-hours are considered "large." Smaller requests for up to 200,000 core-hours are accepted any time and are typically reviewed within two business days.
Unidata is pleased to announce that it will be maintaining a publicly-accessible code repository for the jj2000 software library. jj2000 is a JPEG 2000 encoder/decoder written in pure Java; it is used in the THREDDS Data Server (TDS) and the NetCDF-Java library to support JPEG 2000 compression in GRIB2 files.
JPEG 2000 is an image coding system that uses compression techniques based on wavelet technology. Unlike the older JPEG standard, JPEG 2000 can perform either lossless or lossy compression of data.
NOAA has announced that its Wind Profiler Network (NPN) will be decommissioned this year. NOAA's first step in this process will be to deactivate the NPN data feed to NWS websites and the Unidata IDD network. As a result, CONUS wind profiler data in the IDD FSL2 feed will also cease on or about August 30, 2014.
Read on for the text of the NOAA Profiler Network Service Change Notice announcing the removal of the data feed.
