One of the Expedition 40 crew members aboard the International Space Station photographed this nighttime image showing city lights in at least half a dozen southern states from some 225 miles above the home planet. Lights from areas in the Gulf Coast states of Texas, Louisiana, Mississippi and Alabama, as well as some of the states that border them on the north, are visible. Image Credit: NASA

Independence Pass
The Independence Pass Station was installed and began collecting data in the summer of 2016. Located at an elevation of around 12,080 feet (3,680m), the station is located in an alpine environment characterized by willows. This particular stand is of interest because it is in a high alpine environment. This station is powered by solar panel and measures air temperature, rain, snow depth, relative humidity, soil temperature, and moisture at 2, 8, and 20 inch (5, 20, and 51cm) depths.
The Spring Valley Station was installed and began collecting data in the summer of 2016. Located at an elevation of around 7,100 feet, the station is located in a pinyon-juniper and sageland ecosystem. This station is powered by solar panel and measures air temperature, relative humidity, soil temperature at an 8inch depth, and soil moisture at 2, 8, and 20 inch depths.
The Sky Mountain Station was installed and began collecting data in the summer of 2012. Located at an elevation of around 8,380 feet, the station is located in a stand of aspens. This particular stand is of interest because it occurs on a north-facing slope that is primarily covered with woody shrubs such as sage, scrub-oak, and service berries. This stand of aspens may be a stand in transition. This station is powered by solar panel and measures air temperature, relative humidity, soil moisture at 2, 8, and 20 inch depths. In summer of 2015, soil temperature at 8 inches was added as well.
The Glassier Ranch Station was installed and began collecting data in the summer of 2014. Located at an elevation of around 6,460 feet (1,970m), the station is in a riparian zone near the Roaring Fork River and is surround by tall grasses. This area was heavily impacted by ranching and agriculture previous to its current ownership by Pitkin County Open Space and Trails, and its soil moisture content may still be impacted by nearby irrigation. This station is powered by solar panel and measures air temperature, relative humidity, soil temperature at 8 inches, and soil moisture at 2, 8, 20, and 40 inch (5, 20, 51, and 102cm) depths.
