Spatial and Temporal Variation of Stable Isotopes in Precipitation across Costa Rica: An Analysis of Historic GNIP Records

Sánchez Murillo, Ricardo; Esquivel Hernández, Germain; Welsh, Kristen; S. Brooks, Erin; Boll, Jan; Alfaro Solís, Rosa; Valdés González, Juan (2013-11-27)

The location of Costa Rica on the Central American Isthmus creates unique microclimate systems that receive moisture inputs directly from the Caribbean Sea and the Pacific Ocean. In Costa Rica, stable isotope monitoring ...

Deciphering key processes controlling rainfall isotopic variability during extreme tropical cyclones

Sanchez-Murillo, Ricardo; Durán-Quesada, Ana María ; Esquivel-Hernández, Germain; Rojas-Cantillano, Daniela; Birkel, Christian; Welsh Unwala, Kristen; Sánchez-Llull, Minerva; Alonso Hernández, Carlos M.; Tetzlaff, Doerthe; Soulsby, Chris; Boll, Jan; Kurita, Naoyuki; Cobb, Kim (2019-09)

The Mesoamerican and Caribbean (MAC) region is characterized by tropical cyclones (TCs), strong El Niño-Southern Oscillation events, and climate variability that bring unique hazards to socio-ecological systems. Here we ...

Key drivers controlling stable isotope variations in daily precipitation of Costa Rica: Caribbean Sea versus Eastern Pacific Ocean moisture

Sanchez-Murillo, Ricardo; Birkel, Christian; Welsh, K.; Esquivel-Hernández, Germain; Corrales Salazar, José Leonardo; Boll, J.; Brooks, E.; Roupsard, O.; Saénz - Rosales, O.; Katchan, I,; Arce - Mesén, R.; Soulsby, C.; Araguás Araguás, L. (Elsevier, 2016)

Costa Rica is located on the Central American Isthmus, which receives moisture inputs directly from the Caribbean Sea and the Eastern Pacific Ocean. This location includes unique mountainous and lowland microclimates, but ...

GPS PrecipitableWater Vapor Estimations over Costa Rica: A Comparison against Atmospheric Sounding and Moderate Resolution Imaging Spectrometer (MODIS)

Campos - Arias, Polleth; Esquivel-Hernández, Germain; Valverde, José; Rodríguez - Rosales, Stephanie (MDPI, 2019)

Abstract: The quantification of water vapor in tropical regions like Central America is necessary to estimate the influence of climate change on its distribution and the formation of precipitation. This work reports daily ...

Groundwater and surface water connectivity within the recharge area of Guarani aquifer system during El Niño 2014–2016

Batista, Ludmila; Gastmans, Didier; Sanchez-Murillo, Ricardo; Saeta Farinha, Bárbara; Rodrigues dos Santos, Sarah María; Hung Kiang, Chang (Wiley & Sons, 2018)

Recharge areas of the Guarani Aquifer System (GAS) are particularly sensitive and vulnerable to climate variability; therefore, the understanding of infiltration mechanisms for aquifer recharge and surface run‐off generation ...

Moisture transport and seasonal variations in the stable isotopic composition of rainfall in Central American and Andean Páramo during El Niño conditions (2015–2016)

Esquivel-Hernández, Germain; Mosquera, Giovanny; Sanchez-Murillo, Ricardo; Quesada Román, Adolfo; Birkel, Christian; Crespo, Patricio; Célleri, Rolando; Windhorst, David; Breuer, Lutz; Boll, Jan (John Wiley and Sons Ltd, 2019)

High‐elevation tropical grassland systems, called Páramo, provide essential ecosystem services such as water storage and supply for surrounding and lowland areas. Páramo systems are threatened by climate and land use ...
