The aim of this paper is to provide the community with a comprehensive overview of the studies of glaciers in the tropical Andes conducted in recent decades leading to the current status of the glaciers in the context of ...

A data portal for regional climatic trend analysis in a Peruvian High Andes region

Schwarb, M.; Acuña, Delia; Konzelmann, Thomas; Rohrer, M.; Salzmann, N.; Serpa Lopez, B.; Silvestre, E. (Copernicus Publications, 2011-08-16)

In the frame of a Swiss-Peruvian climate change adaptation initiative (PACC), operational and historical data series of more than 100 stations of the Peruvian Meteorological and Hydrological Service (SENAMHI) are now ...

Potential impacts of early twenty-first century changes in temperature and precipitation on rainfed annual crops in the Central Andes of Peru

Sanabria, Janeet; Calanca, Pierluigi; Alarcón Velazco, Constantino; Canchari, Glicerio (Springer, 2014-03-08)

Smallholder agriculture in the Central Andes of Peru is based to large extent on rainfed cropping systems, is exposed to climatic risks and is expected to respond sensitively to increasing temperatures and shifts in the ...

Afonso, J.M.S.; Vila, D.A.; Gan, M.A.; Quispe, D.P.; Barreto, N.J.C.; Chinchay, J.H.H.; Palharini, R.S.A. (MDPI AG, 2020-07-21)

The main objective of this study is to assess the ability of several high-resolution satellite-based precipitation estimates to represent the Precipitation Diurnal Cycle (PDC) over Brazil during the 2014–2018 period, after ...

Observed and projected hydroclimate changes in the Andes

Pabón-Caicedo, José Daniel; Arias, Paola A.; Carril, Andrea F.; Jhan Carlo, Espinoza; Katerina, Goubanova; Lavado-Casimiro, W.; Mariano, Masiokas; Silvina, Solman; Ricardo, Villalba (Frontiers, 2020-03-17)

The Andes is the most biodiverse region across the globe. In addition, some of the largest urban areas in South America are located within this region. Therefore, ecosystems and human population are affected by hydroclimate ...

Facing unprecedented drying of the Central Andes? Precipitation variability over the period AD 1000-2100

Neukom, R.; Rohrer, M.; Calanca, P.; Salzmann, N.; Huggel, C.; Acuña, Delia; Christie, D.A.; Morales, M.S. (Institute of Physics Publishing, 2015-08)
