Tight Coupling Between Soil Moisture And The Surface Radiation Budget In Semiarid Environments: Implications For Landatmosphere Interactions, Eric E. Small, Shirley A. Kurc
Environmental Science and Geology Faculty Research Publications
Observations are used to examine how soil moisture influences the surface radiation budget, ground heat flux, and available energy in semiarid environments. Defining this relationship is critical to understand interactions between the land surface and the atmosphere, in particular assessing if a feedback exists between soil moisture and rainfall anomalies. We use two summers of data collected from semiarid grassland and shrubland ecosystems in central New Mexico. The response of surface radiation budget components and other variables to soil moisture variations are quantified via linear regression. Then, the variations are scaled over the observed range of soil moisture (15% volumetric …
Depositional Characteristics Of 7Be And 210Pb In Southeastern Michigan, D. Mcneary, M. Baskaran
Depositional Characteristics Of 7Be And 210Pb In Southeastern Michigan, D. Mcneary, M. Baskaran
Environmental Science and Geology Faculty Research Publications
The depositional fluxes in the bulk and dry fallout as well as the concentrations of 7Be and 210Pb in aerosols were measured for a period of 17 months at Detroit, Michigan. The bulk depositional fluxes of 7Be and 210Pb varied between 3.11 and 63.0 dpm cm−2 yr−1 (mean of 11.4 dpm cm−2 yr−1) and 0.35 and 10.3 dpm cm−2 yr−1 (mean of 1.41 dpm cm−2 yr−1), respectively, and this variability in the depositional fluxes is attributed to the frequency and amount of precipitation and seasonal variations …
