THANK YOU


Steve
Callsign W5SDC
Storm chaser, weather station technician, and internet domain linux admin

This station's first weather page went live on the internet in January of 2004. Since then, home weather stations have become much more reliable, affordable, and now provide much more data than just basic temperature, wind, and rain measurements.

It is a pleasure to have a weather station on the web and very honorable to be able to submit instrument readings to NOAA's MADIS database through the CWOP-Citizens Weather Observer Program. I also xmit conditions at 5 min intervals to Weather Underground and findu.com.

My data from Leander, Texas combined with thousands of other private stations from around the world provide invaluable data used for forecasting, nowcasting, and scientific study by students of meteorology and climate.

This station is here solely in the public interest and simply for the greater good that up to date weather information brings everyone.

Thanks for stopping by.

Gary Roderick

Big thanks to Tom Keffer for writing the weeWX weather station engine and also to Matthew Wall and Gary Roderick for their invaluable contributions to weeWX, it's drivers, and it's extensions. Get the whole saga of weeWX and the software at the link above. weeWX is relatively easy to configure and use even for those like me with limited programming experience. On June 26, 2017, I started with the basic HTML template that was included with weeWX and have watched this entire weather website's template grow to 1.953 lines of HTML over the last eight years.



Elwood Downey


Thank You Elwood Downey, WB0OEW for your creation of the astronomical position calculations used in the Heavenly Bodies section of this website. Donating your libastro C calculation library for use in PyEphem for linux was a very gracious thing to do. Many people are grateful for your generosity and hard work on that project and so many others.
