		<abstract>The new IMERG and GSMaP-v6 satellite rainfall estimation (SRE) products from the GPM mission have been available since January 2015. With a finer spatial resolution of 0.1°, these products should provide more accurate information  than their latest widely adapted (relatively coarser spatial scale, 0.25°) counterpart (TMPA product). The present study is a novel attempt, in which the relative performance evaluation of these new products (IMERG and GSMaP) is done by comparing their rainfall estimations with rainfall gauges data of the years 2014 and 2016 in Bolivia. The comparisons were done on annual and monthly scales over the three main national watersheds (Amazon, La Plata and TDPS) at both wet and dry seasons. To observe the potential enhancement in rainfall estimates bring by these two recently released products, the widely used TMPA product is also considered in the analysis. The results differ from product to product as well as from season to season, in spite of these, the results are also influenced by the geographic variations of the considered regions. Generally, the performances of all the products increase during the wet season over all three Bolivian watersheds. TMPA and GSMaP-v6 are the more and less accurate products over the region. Slightly less accurate than TMPA, IMERG can almost fulfill its main objective which is to ensure TMPA rainfall measurements.</abstract>
