    Widespread excessive heat warnings and heat advisories are currently in effect. Also, low humidity and dry thunderstorm potential are adding to the fire danger across the Great Basin and Northwest. Meanwhile, a system is producing heavy rain and flash flood concerns in the Mid-Atlantic. Read More >. Tracking Process. Depending on the antennas rotation rate and pulse repetition frequency of radar it will illuminate targets on a number of transmissions (see: dwell time and hits per scan in chapter “Basics”). In each range cell on each pulse period the signal processing decides whether a target is present, and if so produces a partial report, which defines the information available for.

    These precipitation reports cover 48, and 72 hour periods ending daily at 7 AM EST/8 AM EDT/ UTC. NEW: 6 hour totals; 24 hour total/Text version; 48 hour total; 72 hour total; Multisensor Reports: This data combines gage reports and radar-derived precipitation estimates. Multiple time spans, ranging from 1 to 72 hours, are available.   The original data from NCEP is in GRIB (GRIdded Binary or General Regularly-distributed Information in Binary form) format (files pre-March 22nd, are in XMRG format) and projected in the Hydrologic Rainfall Analysis Project (HRAP) grid coordinate system, a polar stereographic projection true at 60°N / °W.

      Abstract: Doppler weather radar can detect the changes in precipitation clouds for short-term forecasting. In the process of development of Doppler weather radar and weather identification algorithms, some typical Doppler weather radar base data corresponding to different weather phenomena are necessary for signal processing unit test and algorithm verification. Radar-based extreme rainfall analysis Even though radar archives are nowadays a unique resource to investigate the behavior of precipitation, since weather r adar has been widely used for quantitative precipitation estima tion (QPE) for many years, radar data have not yet been extens ively used to derive statistics of extreme rainfall.

Computer software for rainfall analyses and echo tracking of digitized radar data / By Stellan Sven. Östlund, Environmental Research Laboratories (U.S.). Weather Modification Program Office. and United States. National Oceanic and Atmospheric Administration.

Abstract "March "Includes bibliographical references (p. 50).Mode of access. Climatological analyses of manually digitized radar (MDR) data are presented to illustrate geographic, seasonal, and diurnal heterogeneities of precipitation over the United States east of the Rock Cited by:   NOAA's Weather and Climate Toolkit (WCT) is free, platform independent software distributed from NOAA's National Centers for Environmental Information (NCEI).

The WCT allows the visualization and data export of weather and climate data, including Radar, Satellite and Model data. The weather defender software has various programs to connect the desktop to the national network of weather satellites and radar.

It helps in scanning the weather intruders continuously near the place of residence and business. It helps in identifying the weather threats of lightning, tornadoes, hail, high winds and storms.

data were input into ArcView® and basin-average parameters were created for each subwatershed. Radar rainfall data every fifteen minutes were input into the hydrologic model for a recent storm using ModClark, a quasi-distributed runoff procedure in HEC-HMS.

This approach has been adopted so that errors in the radar rainfall data and in the model do not obscure the utility of a good forecast of radar rainfall for flood forecasting. Calibrating the PDM on the flood hydrograph shown in Figure 3, and with radar rainfall as input, achieves a RZ of The miasmatic analysis following Dr.

* Other miscellaneous improvements. The quality of polarimetric radar rainfall estimation is investigated for a broad range of distances from the polarimetric prototype of the Weather Surveillance Radar Doppler (WSRD).

The results of polarimetric echo classification have been integrated into the study to investigate the performance of radar rainfall estimation contingent on hydrometeor type. Rain gage and Doppler radar sites. The subject rain gage for this study, Bear Creek Rain Gage # (see Fig.

1), is an ALERT gage operated by the Coachella Valley Water District (CVWD).An ALERT gage produces a continuous rainfall record by recoding the time at which a pre-selected amount of rainfall is collected in the gage.

Weather radar may be used for forecasting the motion and development of precipitation patterns. A technique is described here which uses digital data sets and a computer pattern‐matching programme to forecast storm motion for periods between one‐half and 2 or 3 hours.

The rainfall-analysis software retrieves real-time radar-rainfall data from a National Weather Service RADAP II (Radar Data Processor), and rain gage measurements from data collection platforms via the Geostationary Operational Environmental Satellite (GOES).

The visualization and decoding of the data requires specialized software. Interactive Radar Map Tool Supplemental data in support of the radar archive, including historical five-minute reflectivity mosaics for the continental United States, radar coverage maps, and map-based site selection tools.

A new radar echo tracking algorithm known as multi-scale tracking radar echoes by cross-correlation (MTREC) was developed in this study to analyze movements of radar echoes at different spatial scales.

Movement of radar echoes, particularly associated with convective storms, exhibits different characteristics at various spatial scales as a result of complex interactions among meteorological.

tial of weather radar data for extreme value analyses and weather radars are nowadays widely used in real-time quantitative precipitation estimation (QPE), radar data have only been used in some studies to derive statistics of extreme rainfall.

This is because the software itself is bundled with a special dongle that is necessary to connect your Vantage Vue or Vantage Pro2 to your computer.

While the software itself is a bit dated, it offers a high degree of customizability on how you can view your data.The real-time observation data is used by the smartphone app "3D Rain Watch" and "RIKEN 3D Nowcast" and the research results of data analysis and data assimilation have been published, but the accurate prediction of torrential rain could not be realized.

Also, many of archived past data .Welcome To Rob's Live Weather Radar Page Welcome to Live Weather Radar I am always looking to improve the weather radars on this site. More Maps will be coming. We fixed are https or SSL certificates, improved load times, improved radar and added your local radar to follow your location.
