TEMPE, AZ (3TV/CBS 5) -

One of the keys to surviving summer in the Valley is to find shade anytime you have to be outdoors and an effort is underway to help pedestrians do just that.

"My work is focused on making the desert environment more comfortable here in the summer," said Ariane Middel, Assistant Research Professor in Arizona State University's School of Geographical Sciences and Urban Planning.

Middel's latest project has her hunting for shade.

"Shade is the most important variable for your thermal comfort, it's even more important than air temperature or humidity or the type of clothing you're wearing," she said.

With that information in mind, she created a mobile tool that measures mean radiant temperatures. 

"That's the radiation that hits your body from all sides," said Middel.

For her research, she pulled the cart around ASU, the sensors collecting data along the way, calculating thermal comfort on a small scale. Then as part of her efforts, she created thermal comfort routing, or mapping the coolest routes on campus. 

"I sampled locations on grass, on an asphalt parking lot, under tree shade, under artificial shade so I tried to sample a lot of different environments," Middel said.

Now that she has the data the idea, is to put it to use making summertime in the Valley a little bit less miserable.

Middel's working on developing a thermal comfort model based off her research so that, "You don't have to measure mean radiant temperature everywhere, you can just model it and apply to the whole city," she said.

The technology is something she's already working with Phoenix and Tempe to put into practice, helping them with their tree planting programs to maximize shade.

"Choosing the right place for the tree is really important, and those measurements can help you assess where those locations are, where your trees give you the most benefit," said Middel.

Looking even further down the road, she wants to create a shade app for people. Right now she says its in the prototype phase.

"The app would route you along the most comfortable path, depending on how long you're willing to walk further," she said.

When it comes to shade on ASU's campus, Middel said her tool determined they could definitely use more shade, something the university is working on.

Amanda Goodman

The Yuma native and ASU Walter Cronkite School graduate is delighted to be back home in Arizona.

Goodman started her career in St. George, Utah, working at an independent station. While there, she was able to do a little bit of everything from reporting to anchoring to shooting her own video and even producing.

From there, she headed east to West Virginia, working at the No. 1 station in the Huntington, Charleston market, WSAZ-TV.

Before returning to Arizona, Goodman spent the past three years at KRQE-TV in Albuquerque. During her time there, she covered many high-profile, stories including the murder trial of a former Albuquerque police officer, the Las Conchas wildfire that threatened Los Alamos National Lab, and the massive Wallow Fire that made its way into New Mexico from Arizona.

When she’s not reporting and tweeting, Goodman spends a lot of her free time hanging out with family and friends.

She also loves to travel and has been to four, soon to be five, continents.

Goodman is so excited to be back home and can’t wait to share some of your stories.

    San Onofre State Beach is a kind of hidden gem among surfers. But there is something about the view here that looks just a little out of place. It’s a nuclear power plant, right on the beach. Some activists want to send the nuclear waste that's housed at San Onofre to Arizona.
