Fall colors by Nader Khoury

The first day of fall is September 22! Ever wonder how weather conditions affect autumn colors? As days get shorter and trees are exposed to less sunlight, the chlorophyll pigment that produces the dominating green color begins to fade, revealing the other colors beneath.

According to the U.S. National Weather Service (NWS), a succession of warm and rainy days means less intense hues, while warm days paired with cooler evenings without frost produce the most brilliant fall colors.

New Heated Magellan MX™ Weather Station Models

Image
Does wintry weather affect the accuracy of your met instruments? Heated sensors can help prevent frozen precipitation from accumulating on weather equipment and causing faulty data. Heated all-in-one sensors are available for the Orion ™ and Pulsar ™ weather stations. Heated wind sensors and tipping bucket rain gauge are available for Capricorn FLX ™ Weather Stations. And now a heated option is also available for the Magellan MX ™ 600, 501, and 500 weather station models. The heating function allows these models to operate easily during snow and ice accumulation with a low power demand (nominally 9W). These Magellan MX models incorporate GPS readings, wind speed and direction, pressure, temperature, relative humidity, and compass. The MX501 adds solar radiation. Magellan MX600 adds rainfall.
