P.E.I. weather app offers real-time readings from 60 locations

A researcher at UPEI has created a new web-based P.E.I. weather and climate app that gives real-time readingsand historical information from across the Island.

"Currently on this app, we have about 60 weather stations showing in real time temperature, precipitation, wind speed and humidity," said XanderWang, an assistant professor in the school of climate change and adaptationat UPEI.

"We also have historical data for climate, so that the people can go into this app to check the current weather conditions but also for the historical conditions."

Localized conditions

Wang said having more than 60 weather stations allows for more localized information, as conditions can vary greatly from one end of the Island to the other.

"Usually people think P.E.I. is a very small Island, and the temperature or rainfall pattern can be very consistent, but in fact it is totally different," Wang said.

"Even for temperature, from East Point to North Capeyou probably see about a fivedegree difference in terms of temperature."

Wang said rainfall patterns can also be totally different.

"That's why we want to put out more stations to capture this kind of spatial difference in the weather conditions."

Downloadable data

Wang said the app's primary audience is the general public, who can check the app on their cellphone or tablet to see current weather conditions.

But he said the hope is that researchers, consultants and government agencies will also use the app.

"It's like an information hub for current weather and historical weather information," Wang said.

"Most importantly, you can download data directly from the app and use itto do analysis."

Wang said the oldest historical data goes back to 1872, from Charlottetown, as well as information collected byEnvironment Canada from weather stations in Summerside andMonticello.

From six to 60 stations

In the past, Wang said, most of the weather information on P.E.I. came from Environment Canada, which currently only has six stations across the Island.

The new app has more sources including information from six stations operated by the P.E.I. Department of Transportation.

The UPEI climate research lab has about 20 stations and there are also weather stations owned by private individuals.

"They also share information with us and we pull information from all of these stations," Wang said.

"We put this into the app and show this information in a real-time basis."

The app includes readings from a new weather station at Lennox Island, whichis also part of astorm surge early-warning systemthat Wang helped to create.

Still gaps

Even with more than 60 weather stations, Wang said there are a few gaps, including west of Summerside.

"In that area, you don't have enough weather stations to show the detailed weather pattern," Wang said.

"So probably, we need to install new stations in the next step."

Wang said the plan is to expand the app to include not just real-time and historical data, but also weather and climate predictions.

"One step we want to do isto incorporate short-term weather predictions so that people can also see what the weather will be in the next two hours, or 20 hours," Wang said.

"Another direction is to incorporate climate projections, into the next 30 or 50, maybe 100 years, to help people understand what will be the future climate on P.E.I."
