abstract = "{Disagreements across different reanalyses over South Asia result into
uncertainty in assessment of water availability, which is
computed as the difference between Precipitation and
Evapotranspiration (P-E). Here, we compute P-E directly from
atmospheric budget with divergence of moisture flux for
different reanalyses and find improved correlation with observed
values of P-E, acquired from station and satellite data. We also
find reduced closure terms for water cycle computed with
atmospheric budget, analysed over South Asian landmass, when
compared to that obtained with individual values of P and E. The
P-E value derived with atmospheric budget is more consistent
with energy budget, when we use top-of-atmosphere radiation for
the same. For analysing water cycle, we use runoff from Global
Land Data Assimilation System, and water storage from Gravity
Recovery and Climate Experiment. We find improvements in
agreements across different reanalyses, in terms of inter-annual
cross correlation when atmospheric budget is used to estimate
P-E and hence, emphasize to use the same for estimations of
water availability in South Asia to reduce uncertainty. Our
results on water availability with reduced uncertainty over
highly populated monsoon driven South Asia will be useful for
water management and agricultural decision making.}",
