CAP LTER weather stations at Papago Park and Lost Dutchman State Park in the greater Phoenix metropolitan area, ongoing since 2010

The CAP LTER maintains two 10-m micrometeorological stations in the
greater Phoenix metropolitan area, including at Lost Dutchman State
Park and near the Desert Botanical Garden at Papago Park. The local
terrain at both sites is flat or gently sloping Sonoran desert, and
the vegetation canopy consists of patchy coverage of desert shrubs and
trees. The dominant vegetation species include bursage (Ambrosia
deltoidea) and creosote bush (Larrea tridentata), while minor species
include palo verde (Parkinsonia microphylla) and saguaro cactus
(Carnegiea gigantea). Wind speed and direction, incoming solar
radiation, air temperature, relative humidity, and precipitation (see
table below) have been monitored nearly continuously since the fall of
2010. Each variable is measured every 5 seconds and the average (or
total for precipitation and total solar radiation) is saved to a data
logger every 10 minutes.
