Interested in using Nexrad Radar
rainfall for historical analysis or in real-time on a tight budget like for free???
GetRealtime is part of a complete system for downloading, processing, storing
radar information with event or continuous runoff simulations (using my simple
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 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. Run your own
system top to bottom for flood analysis and compute loads, DO, and who wants to know that stuff
anyway yourself. This FREE suite of programs and
1) GetMapArea -- For digitizing basin boundaries, runoff
coefficients calibration, rainfall durations, and hydrograph shaping.
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, 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 with muliple runs and traces and what ifs. Routings will
handle most anything short of Grand Coulee for the next 400 years hourly or 30
years at 5-minutes. Has 4 Monte Carlo methods for varying any of the
runoff coefficients and the rainfall record for calibration or stochastic
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).
5) GetGraphs -- For viewing all this stuff
and more in real-time. You will be the master of all you survey, whether that be
a very important sewer
system or just some pretty mountain glacier.
It is all so easy to use that even I can use it!
Get started today and step into the world of tomorrow with
do it yourself
adjusted radar and show the boss a
thing or two and remind him it's free.
Real-time automation of all phases and it repeats every 5 minutes
or as needed. Once your projects are setup, just hit go, sit back, and
behold your creation's glory and smirk at the info starved that will always be
1) Real-time data aquisition--free web weather info needed for ET and snowmelt,
rain gages, other ODBC data connected sources, Nexrad Radar images and rainfall
conversion, and 7-day NWS forecasts.
2) Real-time processing of forecasts, snowmelt, ET, rain gage averaging, radar
rainfall adjustment using much more sophisticated methods.
3) Real-time modeling of runoff or shelling required rainfall and info to
Hec-Hms but mine is better.
4) Real-time soil moisture and groundwater accounting and returns using my
custom methods using SCS Curve Number formulas that are simple to understand and
monitor. Always the right Curve Number at the right time.
5) Real-time post processing the runoff by routing and stage computations or
shelling Hec-Ras for unsteady flow and inundation mapping.
6) Real-time retrieval of any shelled model results storing it all in a REAL
database like MS Access or other ODBC connection.
7) Real-time viewing of your rainfall and runoff values or other info on the
looping GetNexrad radar screen with subbasins and thumbnail plots.
8) Real-time multi-chart and page viewing with alarms of any database value,
rainfall frequencies, web cams or web info. A real war room dream!
9) Or all of the above for any historical event analysis.
Sorry, I don't know anything about GIS so that's one less thing to worry about.
If you don't know where it's at by now, you'll never get hip to this trip. ;-)
Ok, I'm learning.
1) GetRealtime.exe--automated retrieval, computation, and storage of real-time hydrological and meteorological
data available free on the web for continuous computations and simulations.
Specializing in fast NEXRAD and Canada radar dbz conversion to rainfall and adjustment for
runoff simulation for real-time flood alerts or historical studies. Also uses
the 7-day NWS hourly forecast for flood and snowmelt.
GetRealtime.exe started as a simple download of USGS 15-minute flow data. Every
new source added since then is fashioned as if it also were just another USGS
flow station. For example you could think of Nexrad radar rainfall as just another USGS flow
station with a tipping bucket. And runoff is just another computation that
GetRealtime does on the rainfall. Just like converting a USGS gage height to
flow. For Nexrad rainfall all you need are some points to say where the rainfall
of interest is, hence GetMapArea & GetNexrad are used to
provide GetRealtime with these points of interest. GetRealtime uses methods to
provide great results while keeping input needs to a minimum, but still allowing
for options for the pros.
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 or Hec-RAS to do your bidding.
GetRealtime can automate Hec-RAS to do its
unsteady flow routings and read the results back into the GetRealtime system in
real-time and likewise Hec-HMS. 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. GetRealtime is the Ferrari of runoff, as the Commander knows...
2) GetGraphs.exe--displaying a mix of the real-time data and web
screens and gifs by auto paging through screens the user has defined with auto
updating at regular intervals. Some may not be interested in the hydrological
graphs but can still make use of the automated web screens to display multiple
web browsers (up to 12 on one screen) on multiple pages with automated updating
and paging and each can be for browsing further. Also good for monitoring alot
of stuff like Plant Information Management and Quality Control databases with
alarms for any real-time time series database that needs an eyeball on things
now. Just light up that big screen TV monitor with GetGraphs when the boss
is around instead of the ball game.
3) GetAccess.exe--managing and display of the real-time and historical data stored in an
MS Access database (the MS Access runtime can be downloaded for users not owning
MS Office), an Excel database, or other ODBC database. GetAccess can write
the database data to text file or Excel and Excel can write it back with the
GetAccess output xls data editing file. Write Excel files with
HEC-DSS header info for storing to HEC-DSS files using the Excel HEC-DSS AddIn.
GetRealtime and GetGraphs’ example of many auto paging screens...
GetAccess for database management...
Continuous simulations of adjusted radar rainfall-runoff, radar snowpack and
melt, and much more....
Who can make use of the information provided by the GetRealtime system:
1) Home owners and professionals watching local river flood conditions,
rainfall and computed runoff rates, radar loops, temperatures, and live webcams real-time.
2) Anyone wanting to automate viewing of several Web pages on one screen
or many such screens and automate their updating at regular intervals.

their computer screen and compare their thermometer with someone’s down the
8) Skiers monitoring snow depths, weather forecasts, and webcams showing
conditions at all their favorite ski slopes.
9) Professionals wanting to display all their data real-time in their
operations war room on a big screen up on the wall as an excuse to get a big
flat screen TV and impress the boss and visitors.
10) Agricultural commodity traders trying to keep up with it all.
11) Local, County, and Federal fire fighters needing a record of areal average
rainfall for esitmating fire hazard pontential.
12) Agricultural irrigation districts or even a small farmer can outline
their district boundary and compute the 5-minute, hourly, and daily rainfall
amount averaged over their district and adjust their water order accordingly in
real time with out the cost of maintaining a network of rain gages. Combine this with Getrealtime’s
Penman-Monteith standard evapotranspiration computation and you have stepped
into the 21st Century and beyond.

FindMySoft Editor's Review
GetRealtime - view real time weather information
The weather is extremely
important for all of us. It influences our life and our decisions and that's why
it's important to know its condition at all times. There are numerous computer
applications on the market for displaying weather conditions, but none of them
match the complexity of GetRealtime. This Windows application is able to
retrieve real time data from a large number of weather stations worldwide.
Installing this program is a very simple process, as the process is simple to
complete and requires only a couple of clicks for this. After installing and
launching the application, the user will be presented with a simple and
intuitive interface, from where he can choose the desired weather station. This
can be done by opening a large list of weather stations, which can be edited and
the user can add his own stations.
... And some more stuff
