Free Hydrological Weather Radar System

(or just store some USGS and weather data)
Microsoft Windows XP, Vista, 7, 8, 10
The best and easy way to get started with weather radar rainfall runoff and it's FREE! 
GetRealTime = 5 Components

1) GetRealTime.exe - reads and stores data in MS Access DB; pulls data from other networkds, makes calculations, adjusts radar, runs flow models, and forecasts rain events and flows.

2) GetAccess.exe - frontend to the DB; useful for exporting and viewing data but DB is accessible and tables can be viewed and queried directly.

3) GetGraphs.exe - links to DB and websites; allows the viewing of up to 12 charts per view.

4) GetNexrad.exe - view radar images and loops, surface obs, flood forecasts, QPF rings, storm tracks, ETA, and more.

5) GetMapArea.exe - used to georeference radar watershed boundaries and run quick flow model what ifs and rainfall scenarios.

Interested in using Nexrad Radar rainfall in real-time or for historical analysis????
GetRealtime is a complete system for downloading, processing, storing radar information with event or continuous runoff simulations with automated Nowcasts (using my fabulous SCS CN soil moisture accounting)... and no, you do not need GIS software because the NWS is our GIS expert and have already gridded the radar info as 1 kilometer gridded images at highest resolution 0.5 dbZ every 5 minutes. We just average the image pixel color rainfall inside our boundary and skip the GIS. I will show you the steps with several case studies on how it all works in real-time.  And with you at the helm, I bet you can learn how to exceed any commercial service available so why not get started today and get your head in the game.  Run your own system top to bottom for rainfall frequency, flood analysis, and compute loads, DO, and who wants to know that stuff anyway yourself.  Don't see what you need or have some better ideas?... I bet I can add them. Or write your own software that puts or gets data to the GetRealtime database and GetRealtime can shell it and wait. So put the radar the Boss sees on TV on his desk and drag the dullard into Todaysville.

Don't worry, we will not be dealing with gridded radar records or gridded runoff modeling unless you insist on being some sort of masocist with sub par results. Instead of the usual Thiessen polygon weighted watershed rainfall record we substitute the averaged radar rainfall inside the watershed. So the only additional record needed is the adjustment of this radar rainfall record so add a few FREE real-time Wunderground weather stations and viola!... you just entered the 21st Century!  Toss in winds aloft storm track and the 6-hr NWS rainfall QPF's distributed to 5-minutes for the next 7 days and you have entered where few have gone before... Happytown USA in Real-Time!!!  And fast!  A 20 subbasin routing setup with some realtime rain gages for radar adjustments takes less than 30 seconds on my Windows XP.  GetRealtime can set its run time interval based on forecasts so don't sweat the 30 seconds.

In Jargonese, GetRealtime is a comprehensive data acquisition and hydrologic modeling system for short-term decision support of water control operations and flooding potentials in real time. It encompasses data collection, validation and transformation, data storage, visualization, real time model simulation with multi-run saves for later indernment, and data dissemination, and more, and can even use the HEC models RAS, HMS, ResSim and EPA-SWMM.  Just do some Put setup lines, then Shell, and some Get setup lines at any point in your basin setup where these guys can help.

Here is a real world example of GetRealtime installed on a MS Azure Cloud to provide real-time flood aware web services and custormer alerts 24/7 (Walter Schoel Engineering):
Or check out my 24/7 site run off my old laptop to GoDaddy when it's raining here... or snow melting here.  I keep trying to get these professional guys to add some pizzaz but to no avail. They know their customers better than some radar rube's idea for throwing all the spaghetti on the wall like I do.

This FREE suite of programs and functions include:

1) GetMapArea -- For us GIS ignorant (just Google Earth) for digitizing basin boundaries, runoff coefficients calibration, rainfall durations, and hydrograph shaping. This is how you did it before NED's and DEM's and Shapes and Layers, but if you already got your boundary lat/longs the hard way, that's ok too.

2) GetNexrad -- For current visualization of radar imagery, historical analysis, basin area averaging, gridded radar output, QPF forecasting, and radar track Nowcasting... AND storm ETA for NASCAR race fans.

3) GetRealtime -- Downloads current or historical radar imagery, rain gages, flows, forecasts, and computes gage/radar adjustment and applies them, incorporates NWS QPF's, storm track Nowcasts, snowmelt, ET, and then simulates event and continuous runoff and routings with multiple runs and traces and what ifs which means each real-time forecast and runoff comp can also automatically be saved for post event analysis.  Routings will handle most anything short of including hourly scheduled Modpul for Grand Coulee and it's system of dams and irrigation districts for the next 400 years hourly or 30 years at 5-minutes on my 1.3 gig ram XP.  Has 4 Monte Carlo methods for varying any of the runoff coefficients and the rainfall record/generation for calibration or stochastic runoff of as many storms for any period you like.  GetRealtime can write its radar adjusted rainfall or its runoff to Hec-DSS files in real-time so that you could also use Hec-HMS, RAS, ResSim and EPA-SWMM to do your bidding.  GetRealtime can automate RAS or SWMM to do its unsteady flow routings and read the results back into the GetRealtime system in real-time and likewise HMS and ResSim.  An esteemed RAS user retorts, "I've never had such good data to do a complete calibration with before. This is cool!! It used to take about a full day to get the data ready to do calibration runs. Here, we have the hydrology and the hydraulics working hand in hand to produce everything."  Didn't think you could ever run and link the HEC programs with automated data sources and a REAL database... in real-time... well now you can... but unless you are invested heavily in a current large project, why would you.

4) GetAccess -- Stores the inputs and outputs of all of the above in a simple Microsoft Access database that writes directly to and from MS Excel (also HEC-DSS ready format, GetRealtime writes/reads direct dss).  Maintains current and history to keep the Access file within 2 gigs or... use the dreaded SQLserver or other local/remote servers.

5) GetGraphs -- For viewing all this stuff and more in real-time and FTPing it up the channels.  You will be the master of all you survey, whether that is a very important sewer system or just some pretty mountain glacier.

So where do I start???  
Kick start a fully operational download project for radar rainfall runoff at Nashville from my Site Map page at Start Here!  Unzip and just start running it.  For details read do it yourself adjusted radar.  For an historical example at this site see the epic 2010 Nashville storm on a small 12 sqmi basin.  And email me your questions because you will have them and I expect you to have the best results possible.
