Title: Assessment of Surface Water Storage trends for increasing groundwater areas in India

Abstract: Recent studies based on Gravity Recovery and Climate Experiment (GRACE) satellite mission suggested that groundwater has increased in central and southern parts of India. However, surface water, which is an equally important source of water in these semi-arid areas has not been studied yet. In the present study, the study areas were outlined based on trends in GRACE data followed by trend identification in surface water storages and checking the hypothesis of causality. Surface Water Extent (SWE) and Surface Soil Moisture (SSM) derived from Moderate-resolution Imaging Spectroradiometer (MODIS) and Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) respectively, are selected as proxies of surface water storage (SWS). Besides SWE and SSM, trend test was performed for GRACE derived terrestrial water storage (TWS) for the study areas named as R1, R2, GOR1 and KOR1. Granger-causality test is used to test the hypothesis that rainfall is a causal factor of the inter-annual variability of SWE, SSM and TWS. Positive trends were observed in TWS for R1, R2 and GOR1 whereas SWE and SSM show increasing trends for all the study regions. Results suggest that rainfall is the granger-causal of all the storage variables for R1 and R2, the regions exhibiting the most significant positive trends in TWS.

Indian Institute of Remote Sensing (IIRS), a Unit of Indian Space Research Organisation (ISRO), is a premier institute for capacity building and research in the field of remote sensing and geoinformatics. IIRS invites applications for the posts of scientist/engineer-SC.

Can anyone tell me what is the difference between Seasonal and Interannual variation with some suitable example ? I have searched a number of places but the definition of the terms are not clearly stated.

Data / Orbiting Carbon Observatory 2
« on: September 12, 2014, 08:30:55 PM »
This a new satellite launched on 2nd July 2014. Earth satellite mission designed to study the sources and sinks of carbon dioxide globally.

Researchers who study the interaction of plants, carbon and climate are eagerly awaiting data from NASA's upcoming Orbiting Carbon Observatory-2 mission on a nearly invisible fluorescent glow emitted from the chlorophyll contained within plants. Hence this can also be useful for hydrologists.

The first link below talks about the mission. The second one describes the alternative use that it can be put into.

Announcements / Introduction

Dear Sat and all moderators

I have an Idea:
Once a person joins the forum, if they can be automatically directed to the Introduction board, as a part of being a member, we will easily get to know who has joined and they will get a feel how to post and better familiarize with the forum.

Secondly, the forum is slow I feel, can we do something about it ?

Hello All

We need to make the forum more active and increase the number of meetings.
Let us all first make sure that all the present students of the WREE group have joined the forum.
Secondly we should start inviting our alumni in the forum and publicize the facebook page (
