Level 3 data combines Level 2 data to provide additional information about the precipitation and air around the radar site. A successful test will generate several .json files in the ./output folder.

A javascript implementation for decoding Nexrad Level III radar files. 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. Looking for U.S. government information and services. Part I: The Pre-NEXRAD Era, History of Operational Use of Weather Radar by U.S. 2015-04-22T00:00:00 - NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. Click here Data and corresponding output are provided for quick and easy testing and experimentation. Categorize messages generated by node, such as reading past the end of the buffer as errors, and log them as errors. |0x0020|Special Graphic Symbol Packet| The parser will read files as either a string or a buffer. 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. NOAA's Climate.gov created an article and video introduction to the Weather and Climate Toolkit. The NEXRAD products are divided in two data processing levels. 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 makes some rudimentary checks to confirm data is valid. lock ( The recommended practice is to test that your desired data structure exists in the returned object before doing any further processing with it. With the advent of dual polarization beginning in 2011, additional base products of differential reflectivity, correlation coefficient and differential phase are available. The NEXRAD system detects precipitation and wind, and its data can be processed to map precipitation patterns and movement. This text is returned as symbology.pages, but is technically undocumented per the specification above. According to the ICD for the Product Specification , "the 256 data levels of the digital product cover a range of reflectivity between -32.0 to +94.5 dBZ, in increments of 0.5 dBZ. These include storm structure, hail index, mesocyclone identification, tornadic vortex signature, and storm tracking information. Unidata inquiry tracking system and then made publicly available 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. In production it has been found that some NSS data includes symbology IDs other than 1 which is the only one that appears in the documentation. A product which shows an intense gate-to-gate azimuthal shear, associated with tornadic- scale rotation. |170|DAA|Digital One Hour Accumulation Use liability: NOAA and NCEI cannot provide any warranty as to the accuracy, reliability, or completeness of furnished data. The data are sent to the National Climatic Data Center for archiving and dissemination. Before you start getting the data, decide what you want to do with it by adding lines to your pqact.conf configuration file for decoding or filing the data. 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. File Compression: Unix Zip (.Z) or gzip (.gz) compression and tape archive (.tar) may be applied to data files retreived from the NCDC archive. Other cases of truncated data may also exist. 2620001 ICD FOR THE RPG TO CLASS 1 USER - Build 19.0, https://www.roc.noaa.gov/wsr88d/PublicDocs/ICDs/2620001Y.pdf, https://www.ncdc.noaa.gov/data-access/radar-data/nexrad-products, https://registry.opendata.aws/noaa-nexrad/.

Any individual block may be corrupt, but this code will continue to try the additional pointers. A custom logger such as winston or pino can be provided. #1 I know that Iowa State has a Level II data feed for free, but which is susceptible to overloading on significant days, and Allisonhouse has the more robust feed for a monthly fee. nexrad-level-3-data A javascript implementation for decoding Nexrad Level III radar files. In some situations additional data is provided in the productDescription property including a friendly name for the type of data or product legends to aid in decoding the data. I've developed parsing algorithms for that the products that I needed most for my own use. The Level 3 data consists of reduced resolution, low-bandwidth, base products as well as many derived, post-processed products. NEXRAD is a network of 160 high-resolution Doppler weather radars operated by the NOAA National Weather Service (NWS), the Federal Aviation Administration (FAA), and the U.S. Air Force (USAF).

Because the data is made up of a header containing pointers to other parts of the file. You can create your own algorithm to determine rain rates based upon reflectivity values. Level II data only consists of Base Reflectivity (0.5 dBz increments), Radial Velocity (1kt increments), and Spectrum Width. Please let me know of any questions. NEXRAD is a network of 160 high-resolution Doppler weather radars operated by the NOAA National Weather Service (NWS), the Federal Aviation Administration (FAA), and the U.S. Air Force (USAF).

Scientists use these products to estimate wind speed and direction, locate boundaries, locate severe weather signatures, and identify suspected areas of turbulence. The DVL version of the product provides a higher spatial resolution and enhanced processing. During 2008, the WSR-88D radars were upgraded to produce increased spatial resolution data, called Super Resolution.
