Abstract:

HOBO micromet station are located at the three permanent plots, presidents house, desert botanical garden, and community services building. All stations are equiped with temperature, humidity, and PAR sensors. The station at the DBG is part of an experimental setup in which different watering regimes are tested. At the presidents house soil temperatures and moisture is measured at 3 depth. At the community services building soil temperature and moisture are measured at the same depth under a shrub, in a swale and a slope.
