Terrestrial water storage changes across the contiguous United States from GPS and GRACE, 2007–2017

In this dataset, we provide terrestrial water storage anomalies (TWSA) from 2007-2017 at weekly time scales derived using Global Positioning System (GPS) displacements, further constrained by lower-resolution TWSA observations from the Gravity Recovery and Climate Experiment (GRACE). There are six fields in the HDF5 product provided here: '/cmwe', which provides terrestrial water storage in units of cm. of water equivalent. '/latitude', latitude at the center of each 0.5 degree grid cell /longitude', longitude at the center of each 0.5 degree grid cell '/time', time in days since January 1st, 2007. The resolution of our time series is weekly, and the first day in our record is January 3rd, 2007. '/signal_to_noise_ratio', the variance of the signal divided by variance of noise for each grid cell in the dataset. Please read the supplementary information document in the paper below for more details. '/uncertainty', 95% confidence interval for each grid cell in the dataset. Please read the supplementary information document in the paper below for more details.
