Comparative ground validation of IMERG and TMPA at variable spatiotemporal scales in the tropical Andes
(American Meteorological Society, 2017-09)
An initial ground validation of the Integrated Multisatellite Retrievals for GPM (IMERG) Day-1 product from March 2014 to August 2015 is presented for the tropical Andes. IMERG was evaluated along with the Tropical Rainfall ...

The influence of station density on climate data homogenization
(John Wiley and Sons Ltd, 2017-11)
Relative homogenization methods assume that measurements of nearby stations experience similar climate signals and rely therefore on dense station networks with high-temporal correlations. In developing countries such as ...

Hydroclimatic change disparity of Peruvian Pacific drainage catchments
(Springer-Verlag Wien, 2017-08-23)
Peruvian Pacific drainage catchments only benefit from 2% of the total national available freshwater while they concentrate almost 50% of the population of the country. This situation is likely to lead a severe water ...

Regional maximum rainfall analysis using L-moments at the Titicaca Lake drainage, Peru
(Springer-Verlag Wien, 2017-08)
The present study investigates the application of the index flood L-moments-based regional frequency analysis procedure (RFA-LM) to the annual maximum 24-h rainfall (AM) of 33 rainfall gauge stations (RGs) to estimate ...

The freezing level in the tropical Andes, Peru: An indicator for present and future glacier extents
(Wiley-Blackwell, 2017-10)
Along with air temperatures, the freezing level height (FLH) has risen over the last decades. The mass balance of tropical glaciers in Peru is highly sensitive to a rise in the FLH, mainly due to a decrease in accumulation ...

Regionalization of rainfall over the Peruvian Pacific slope and coast
(John Wiley and Sons Ltd, 2017-01)
Documenting the heterogeneity of rainfall regimes is a prerequisite for water resources management, mitigation of risks associated to extremes weather events and for impact studies. In this paper, we present a method for ...

Hydrological and depositional processes associated with recent glacier recession in Yanamarey catchment, Cordillera Blanca (Peru)
(Elsevier B.V., 2017-02)
In this study, we investigate changes in the glaciated surface and the formation of lakes in the headwater of the Querococha watershed in Cordillera Blanca (Peru) using 24 Landsat images from 1975 to 2014. Information of ...
