National Weather Service Raw Upper Air Observational Data - Monthly
NWS Raw UA Obs - Monthly
These National Weather Service (NWS) raw upper air data contain flight data from sites monthly. Majority are Radiosonde Replacement System (RRS) sites, spanning about 7 to 72 degrees latitude and -171 to 172 degrees longitude. Data go back to 2003 to present operational flights. Non-RRS historically, and currently, submit a monthly data package containing a "H" ASCII flight metadata file a "T" ASCII mandatory for each flight conducted during the month. They also submit a third, higher resolution data file, although in some cases NCEI does not have a decoder for those data.
These raw observations are inputs to NWS Radiosonde Standard Levels data (DSI 6301), where the data are encoded at each site using the World Meteorological Organization Binary Universal Form for the Representation of meteorological data (BUFR) format, then packaged with briefer ASCII formatted flight data and transmitted to NCEI via a push to NCEI's FTP from individual sites.

Purpose | High vertical resolution upper air data permits fine-scale analysis of such fundamental atmospheric parameters as temperature, humidity and wind speed. These data also facilitate studies of phenomena with vertical dimensions that span the scales below those of standard radiosonde data resolution: gravity waves, turbulence, tropopause, planetary boundary layer |

Lineage Statement | Data are packaged and uploaded directly from individual upper air sites. Except for validation of flight date / time and the site's WBAN (Weather Bureau Army Navy) ID, no quality control is performed on the data. |

Processing Steps |
|
Processing Environment | Data are currently collected from radiosondes using a variety of radiosondes ground equipment. While the majority of sites have migrated to NWS Radiosonde Replacement System equipment, beginning in 2005, some sites continue providing a monthly package of flight data from non-RRS systems. Other ground equipment may be used in the future. |
