One of the joys of having a website is the new contacts, sometimes leading to friendships, with people who are current or potential cloud/winter storm lovers. Browsing my website, has provided one avenue. Now, I invite you to contact me using the contact form with your weather question, or a comment you have on the site.

I will do my best to get back to you wherever you may be around the world. Looking forward to hearing from you.


Wireless Weather Station

The Model Davis Vantage Pro2 wireless weather station is one of the best weather station I used so far. The wireless Vantage Pro2 can transmit and receive date up to 1000' (300 m). You can get all current weather conditions including; wind speed, wind direction, outside and inside temperature and humidity, barometric pressure, rainfall, solar radiation ... End of 2008, I added an extra Tmp/Hum wireless sensor to mesure weather condition at 1.5 meter level.

Weather software: GraphWeather (highly recommended), Weatherlink (necessary), wsWin (great potential), Cobian Back-up

Development tools: WebDeveloper, Firebug, UltraEdit

Definition : In technology, a mashup is a web application that combines data from more than one source into a single integrated tool; an example is the use of cartographic data from Google Maps to add location information to real-estate data, thereby creating a new and distinct web service that was not originally provided by either source.

To access the Montreal area map with Mashup technology:
