Sentences with phrase «water balance estimates»

«For this study, GRACE served as a unique tool that provided information on water volume changes directly from space, and corroborated the water balance estimates,» said Hyongki Lee, a co-author of the study and a professor of civil and environmental engineering at the University of Houston.

GRACE estimates align with the water balance estimates, with some variance.

Researchers used two methods to track groundwater levels, traditional water balance estimates — which take into account surface water inflow like rainfall and snow melt, soil moisture capacity and evapotranspiration — and data from NASA's twin satellite system called GRACE (Gravity Recovery and Climate Experiment).

Based on the Coca - Cola system's global water replenishment projects to date, the system is balancing the equivalent of an estimated 94 percent of the water used in its finished -LSB-...]

Based on estimated global virtual water trade flows, national virtual water trade balances can be drafted, but getting countries to agree on creating a fair market for water isn't easy.

«Although both water balance - based and GRACE - based groundwater volume estimates are subject to errors, the relatively small area of the Central Valley in the eyes of GRACE might also be responsible for that recovery discrepancy,» Lee said.

This sensitivity estimate is not the last word on the subject, because of uncertainties in the approximate formulae used to compute the terms in the energy balance, and neglect of possible effects of water vapor feedback on the surface budget.

Forest impoverishment due to such fires may increase dramatically when severe droughts provoke forest leaf - shedding and greater flammability; our regional water - balance model indicates that an estimated 270,000 km2 of forest became vulnerable to fire in the 1998 dry season.

If 1 C has been estimated incorrectly, what is the number if you do the estimation using «the full surface energy balance equation (but without water vapor feeback, etc).»?

The main objectives of this study are to better understand the characteristics of the SR through an in - depth assessment of the contemporary water balance when the basin was intensively monitored (1996 — 2005), to use standardized runoff to select the best timescale to compute the Standard Precipitation (SPI) and Standard Precipitation Evaporation Indices (SPEI) to estimate trends in water availability over 1919 to 2005.

The 2003 — 08 specific mass balance for our entire HKKH study region was − 0.21 ± 0.05 m yr − 1 water equivalent, significantly less negative than the estimated global average for glaciers and ice caps4, 10.

Presenting such alternative figures confuses and undermines the public understanding of the actual science, which is an understanding about the driving mechanisms of sea level rise: thermal expansion of ocean water, melting of mountain glaciers and complex dynamics of large ice sheets — in correspondence again with projected temperature rise, that is in turn a product of projected rises of greenhouse gas concentrations using calculated estimates of climate sensitivity, together creating a net disturbance in Earth's energy balance, the very root cause of anthropogenic climate change.
