Seminar title: Global Terrestrial Water Storage Reconstruction Using Cyclostationary Empi rical Orthogonal Functions (1979–2020)

FLAME Uni versity is organizing a seminar on Global Terrestrial Water Storage Reconst ruction Using Cyclostationary Empirical Orthogonal Functions (1979–2020) on Wednesday, January 18, 2023 from 2:30 pm to 3:30 pm at Ramanujan 101 at FL AME University. Prof Hrishikesh Chandapurkar will be delivering the seminar on this topic dealing with the critical issue of water stress at the globa l level.

Satellite-based remote sensing methods provide invaluable ob servations of climate variables. However, several satellite missions are qu ite recent. Is it possible to use the covariability between climate variabl es and the longer records of some climate variables to extend the record of some recent missions? 

Since 2002, Terrestrial water storage (TWS) a nomalies derived from the Gravity Recovery and Climate Experiment (GRACE) m ission have been useful for several earth science applications, ranging fro m global earth system science studies to regional water management. However , the relatively short record of GRACE has limited its use in understanding the climate-driven interannual-to-decadal variability in TWS. 

In a recently published study, these timescales were targeted and a novel method of cyclostationary empirical orthogonal functions (CSEOFs) was applied alo ng with the covariability of TWS with precipitation and temperature to reco nstruct the TWS record for 1979–2020. 

Based on the above, th e seminar will highlight the following:
