It also creates confusion, as on Thursday 3 April, when the IEM webfarm grinds to a halt, but the nexrad service chugs along happily. Testing for the correct value for known separators and other fixed values in the specification. This allows the radar to better distinguish between types of precipitation (e.g., rain, hail and snow), improves rainfall estimates, improves data retrieval in mountainous terrain, and aids in removal of non-weather artifacts.

This is a 10 cm wavelength (S-Band) radar that operates at a frequency between 2,700 and 3,000 MHz. Streams are not supported. Part I: The Pre-NEXRAD Era, History of Operational Use of Weather Radar by U.S. Some easier to understand forms of this data include: Level 3 data is available in real-time through the AWS S3 bucket s3://unidata-nexrad-level3/, Additional documentation on the AWS bucket is available at https://registry.opendata.aws/noaa-nexrad/, The file naming convention is: SSS_PPP_YYYY_MM_DD_HH_MM_SS The parser will return an object representing the data as defined in https://www.roc.noaa.gov/wsr88d/PublicDocs/ICDs/2620001Y.pdf. The upgraded Super Resolution data provides radar reflectivity at 0.5 degree azimuthal by 250 m range gate resolution to a range of 460 km, and Doppler velocity and spectrum width at 0.5 degree azimuthal by 250 m range gate resolution to a range of 300 km. I suspect you would want the level III data as it more accurately delivers what I think you want ( 1 & 3 hour storm totals, and storm total precip) and also the floater FNEXRAD to get the 1 Km mosaic of base reflectivity. Folks using the redirect think the actual level II website is down or very slow, when it is actually fine. |0x0016|Cell Trend Data Packet| nexrad-level-3-data. The radar system operates in two basic modes: a slow-scanning Clear Air Mode (Mode B) for analyzing air movements when there is little or no precipitation activity in the area, and a Precipitation Mode (Mode A) with a faster scan for tracking active weather. Level II data only consists of Base Reflectivity (0.5 dBz increments), Radial Velocity (1kt increments), and Spectrum Width. Errors will be logged to the console for the data which has intentional errors, but the data that can be parsed will still be returned from each file. The parser makes some rudimentary checks to confirm data is valid. Doppler radars detect atmospheric precipitation and winds, which allow scientists to track and anticipate weather events, such as rain, ice pellets, snow, hail, and tornadoes, as well as some non-weather objects like birds and insects. This book describes the needs for end user communities, focusing in particular on needs that are not being met by current urban-level forecasting and monitoring.
