Observed Changes In Climate And Streamflow In The Upper Rio Grande Basin, Shaleene Chavarria
Observed Changes In Climate And Streamflow In The Upper Rio Grande Basin, Shaleene Chavarria
Earth and Planetary Sciences ETDs
Observed streamflow and climate data are used to test the hypothesis that climate change is already affecting the streamflow volume derived from snow accumulation in ways consistent with climate model-based projections of 21st century streamflow. Annual and monthly changes in streamflow volume and surface climate variables on the upper Rio Grande (URG) near its headwaters in southern Colorado are assessed for water years 1958-2015. Trends in discharge are examined together with variations in snow water equivalent and surface climate variables. Results indicate that temperatures in the basin have increased significantly primarily in the winter and spring seasons, April 1 snow …

The isotopic composition of atmospheric water vapor (1H216O, H218O, and 1H2H16O) was continuously measured at the National Oceanic and Atmospheric Administration (NOAA) Mauna Loa Observatory (MLO) from April 8, 2016 through March 13, 2017 using Off-Axis Integrated Cavity Output Spectroscopy (OA-ICOS). The dataset has been carefully corrected for humidity-dependent biases and calibrated against the international VSMOW-SLAP scale to provide a precise, continuous, nearly yearlong dataset from a dynamic subtropical setting. The measurements are provided with 15-minute and 6-hourly resolution.
