Groundwater volume loss estimates over Central Valley California associated with Water Resources Research Publication: Sustained Groundwater Loss in California’s Central Valley Exacerbated by Intense Drought Periods by Ojha et al. 2018
This dataset contains rate of groundwater volume loss based on 1-D poroelastic model applying InSAR vertical land motion observations over Central Valley, California, from December 24th, 2006 to January 1st, 2010. Details of the processing are provided in the work of Ojha et al. (2018):
C. Ojha, M. Shirzaei, S. Werth, D. F. Argus, T. G. Farr, Sustained Groundwater Loss in California’s Central Valley Exacerbated by Intense Drought Periods. Water Resour. Res. 54, 4449–4460 (2018).
Groundwater volume loss changes are provided on a regular grid of grid spacing 0.01 degree. Latitude and longigute coordinates of the grid are provided in the files lat.csv and lon.csv. Groundwater volume loss changes are provided in the file vollow.csv with the grid orientation latitude (rows) by longitude (columns). The groundwater volume loss changes are given in “equivalent water height” in unit of cm.
THIS 3-YEAR PROJECT IS COLLABORATION BETWEEN SCIENTISTS FROM TWO UNIVERSITIES (ASU AND BGSU) AND JPL WITH THE AIM TO SIGNIFICANTLY IMPROVE RESOLUTION AND ACCURACY OF CURRENT ESTIMATES OF TOTAL WATER MASS BUDGET VARIATIONS OVER CALIFORNIA. THE SUCCESS OF T
