See Scott Slater. Scott has had a weather station in many stationary locations, including his home and vacation property since 1998. This made Scott very happy. But Scott and his wife love to camp and take to the open roads in their travel trailer, and this made Scott very sad.

Hear Scott lament: “I can’t be without my weather stations, even on vacation!”

So Scott, being Scott the Brilliant, decided to install a station on his travel trailer, “with little effort and cost.”

“The criteria in my design,” Scott told us, “was that I needed to have a setup that was secure as well as quick and easy to set up and take down while camping. I purchased two 8′ [2.4 m] sections of extension pipes which can lock together with a push button. One of the two sections pipes gets cut, one end of the cut pipe mounts permanently to the tongue jack with clamps, the other end of the cut pipe mounts to the base of the sensor suite. The full section of pipe basically mates with the pipe on the base of the sensor suite, with the opposite end mating with the pipe permanently attached to the tongue jack. It sets up and comes apart in less than 30 seconds. The console is mounted inside the trailer using heavy duty Velcro.”

Now see Scott. He is one happy camper.

“It works like a charm, is easy to set up and put away, and makes weather on the road a blast. Even my wife is finding the weather station is an essential part of camping.”

And one happy Davis customer! “I really enjoy Davis weather equipment. It’s so reasonably priced, reliable, robust, accurate and intuitive too. Plus the technical team is always a pleasure to work with if I have a problem, which I have to say has been a long, long time ago. Thanks, Davis for making such great weather instruments that are versatile enough to be used in so many places.”

This allows the pipe to be rotated so the sensor suite points north. The top pipe mounted to the sensor suite mates with the full section securely with the push button.

Introducing AeroCone: the new aerodynamic rain cone from Davis!

Introducing AeroCone!


There’s a new shape in your future! Vantage Pro2‘s rain collector has gone from its nice, solid, tapered barrel shape, to a wasp-waisted, aerodynamic silhouette!

Our engineers looked at what happens when a high wind gust whips the rain sideways toward the collector.

With the classic shape, the wind hits the collector, and then flows up and over. This turbulence causes the flow to accelerate over the top, and can whip some of the precipitation right past the mouth of the cone. The error is usually small, depending on the speed of the gust and the rain rate, and lasts only as long as the gust.

But since we are always looking for the best of accuracy, even in the worst of conditions, we did a little remake of the shape. The new shape, besides looking totally awesome, allows the wind to go around the rain collector, reducing the turbulence that can create an error.

new cone shape better for high winds
AeroCone’s shape allows wind to flow around the cone, reducing turbulence and friction at the mouth of the collector.


Upgrade to AeroCone!

While they were at it, the design team added a notching system inside the cone that allows the debris screen to lock in. No more blown out debris screens!

The new rain cone is called AeroCone, and is currently shipping with all our new Vantage Pro2 stations. It is backward compatible with all Vantage Pro2s, so if you live where wind gusts are common and would like to reduce this wind-driven rain error, you can just switch out the new cone for the old with an AeroCone Replacement Kit.

However, if you currently have a rain collector heater, you won’t want to order the new cone. The rain collector heater is compatible only with the classic style cone. (What about future AeroCone owners who want a rain collector heater, you ask? Never fear. They’ll be able to get a classic shape cone with the heater. )

Some of these guys are already in the field! Check out this one, installed by Ed Mansouri of WeatherSTEM at Heinz Field in the Pittsburgh Steelers livery.

Vantage Pro2 sporting Pittsburgh Steelers colors!
That, if we do say so ourselves, is a beautiful weather station. Go Steelers!

Vantage Vue knocked down by Hurricane Matthew

This Vantage Vue was ripped from her mount, floated off on the storm surge, and dumped back on the beach. After a little TLC, the sensor suite was back to work!

When Hurricane Matthew had finally passed over Charles Huck’s home in South Ponte Vedra Beach, Florida, in October, Charles ventured out to assess the damage. He found an old friend, down, but far from done. His Vantage Vue was ripped from her mount, floated off on the storm surge, and dumped back on the beach, where Charles found her lying in the weeds. The wind speed shaft was too bent to work, and she was full of sand and seawater, but after a little TLC, the temperature, humidity, wind direction, and rain gauge were all quickly back in working condition.

Hey, when we say we built that thing to be tough, we meant it. Thanks Charles!

Weather system in museum in Spain

Our Spanish distributor, Darrera, is taking Davis weather technology to the people of Spain. First they hit the airwaves, showing off the Vantage Pro2 on the program El Escarabajo Verde on Spanish public TV.

Then they hit the CosmoCaixa Science Museum of Barcelona, one of the most important museums in the country on environment, nature and space, where they installed a new set of interactive weather experiments.

“The different experiments showcase in a fun and engaging way how wind, temperature, humidity, rain, and solar and UV radiation are measured,” Darrera’s Marc Arazo told us. “As you can see, they work thanks to Davis sensors.”

“Each experiment is connected to an analog panel meter that reflects the changes as they occur, and is also accompanied by a touch screen monitor that shows real-time weather data from the Davis station located on the CosmoCaixa rooftop, as well as visual and textual explanations about each specific variable. All the weather data from the rooftop station is stored in a Weathercloud meteOS server, which features a stylish browser-based user interface.”

“One important thing,” he wrote of the sensor suite on the roof, “was to separate the rain gauge from the tower so rain would not be affected, while being able to install the anemometer at the top. The whole system is protected with our new stainless steel-copper lightning protection kit and a surge protector.”

Here is a YouTube video of the rain collector’s tipping bucket in action.

Gorgeous installation, Marc! Gracias por las fotos!

The Charles family of Foursight Wines

The Charles family, Bill and Nancy Charles and their daughter and son-in-law Kristy Charles and Joe Webb, with two other important members of the wine-making team.

The Charles family has been working a piece of land in the lovely Anderson Valley of California for generations. But in 2006, Bill and Nancy Charles, along with their daughter and son-in-law, Kristy Charles and Joe Webb, opened Foursight Wines and began to produce small lots of estate-grown Pinot Noir, Semillon, and Sauvignon Blanc.

Anderson valley fog

The Anderson Valley has crazy temperature swings, but those extremes are often pleasingly moderated by fog.

The Anderson Valley, just outside of Boonville and just west of the famed Napa Valley, is one of the most unique wine-producing areas in the world. Growers there work with some of best—and some of the most extreme—weather conditions in the wine-making world. It’s cool and coastal with the long sunny days of California summers, but it is also a long, narrow valley that channels whipping winds. It also has crazy temperature swings, which can be very good—or very bad—for wine grapes. The valley is known for the highest diurnal temperature swings in the wine-growing world. Joe, who is Foursight’s winemaker and President of the Anderson Valley Wine Association, has recorded a 62-degree swing in one day, going from 107°F (42°C) in the afternoon to 45°F (7°C) that night. This is actually a very good thing, he told us. The extreme swings in temperature add to the quality of the grapes. Daytime highs provide a richness and fullness of the flavor to the fruit, while night time cool weather keeps the acidity of the grapes high—very good for premium wine grapes. But low temps can also lead to crop loss. Then there’s the wind. The winds change direction and speed on a daily basis. Warmer, drier winds zip out of the southeast to dehydrate the air, while cool winds bring in moisture from the northeast.

How could the growers cope with wind and temperature changes that vary more than any wine growing region in the world?

For the first few years, the weather sometimes won the battle. The first year’s production amounted to about 400 cases of Pinot Noir. Not bad, but the Charles’s knew they could do better. While each year was better than the last, the weather continued to be both their greatest asset and their greatest nemesis.

In 2008, the weather was particularly devious and Foursight Wines lost nearly half their crop to an early spring frost. It was clear that the only way they would end this battle with the elements would be to know their enemy! They knew they needed weather stations in each vineyard. However, the 15 acres that was hit hardest by the frost is over half a mile from the winery. How could they track weather conditions 24/7 in remote vineyards?

That’s when Vantage Connect and Vantage Pro2 came to the rescue! The Charles family now tracks conditions in all their vineyards, including the two most remote areas, on their tablets and smartphones. When temperatures drop to near 30°F (0°C), Vantage Connect sends text messages so the growers can turn on overhead sprinklers to raise the temperature to avert frost damage. They can see when a temperature inversion is putting a virtual lid on their vineyard and can turn on fans to mix the air. They can track growing degree days to help determine when the fruit is ready for harvest. And the best part is that they can see these weather events from the comfort of the winery, their bedrooms, or even from their vacations in Lake Tahoe or Hawaii.

This year Foursight Wines hopes to meet its goal of 1500 cases of sublime wine, glowing with a uniqueness that could only come from grapes grown in this special valley. While Mother Nature will never bow to our human authority, Vantage Connect and Vantage Pro2 has let the Charles family make her a true partner in the process.
