District-Level Training and Dissemination of Seasonal Rainfall Forecast por Umer, Yakob, Wapamesa, A, Makungwe, M., Mwase, R., Chongo, T.

“…Presentations highlighted how seasonal forecasts are produced, interpreted, and localized from regional to district levels, with emphasis on understanding the role of major climate drivers such as the El Niño–Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD). Dissemination activities at camp and community levels demonstrated farmers’ ability to understand and apply forecast information when communicated through participatory and localized methods, including the use of vernacular languages and visual aids. …”

A new climate dataset for systematic assessments of climate change impacts as a function of global warming por Heinke, J., Ostberg, S., Schaphoff, S., Frieler, K., Muller, C., Gerten, D., Meinshausen, M., Lucht, W.

“…A pattern-scaling approach is applied to extract generalised patterns of spatially explicit change in temperature, precipitation and cloudiness from 19 Atmosphere–Ocean General Circulation Models (AOGCMs). The patterns are combined with scenarios of global mean temperature increase obtained from the reduced complexity climate model MAGICC6 to create climate scenarios covering warming levels from 1.5 to 5 degrees above pre-industrial levels around the year 2100. …”

Tracer hydrology of the data-scarce and heterogeneous Central American Isthmus por Sánchez-Murrillo, Ricardo, Esquivel-Hernández, Germain, Corrales-Salazar, José L., Castro-Chacón, Laura, Durán-Quesada, Ana M., Guerrero-Hernández, Manuel, Delgado, Valeria, Barbereba, Javier, Montenegro-Rayo, Katia, Calderón, Heyddy, 10 autores más.

“…Groundwater and surface water isotope ratios depicted the strong orographic separation into the Caribbean and Pacific domains, mainly induced by the governing moisture transport from the Caribbean Sea, complex rainfall producing systems across the N-S mountain range, and the subsequent mixing with local evapotranspiration, and, to a lesser degree, the eastern Pacific Ocean fluxes. Groundwater recharge was characterized by (a) depleted recharge in highland areas (72.3%), (b) rapid recharge via preferential flow paths (13.1%), and enriched recharge due to near-surface secondary fractionation (14.6%). …”

Variations in bioavailability of dissolved organic matter during a spring flood episode in northern Sweden por Eriksson, Tobias

“…Therefore, it is likely that most of the bioavailable DOM will be utilized outside the catchment of Krycklan and spring-flood contributions can, consequently, play an important role for carbon and nutrient cycling in rivers, lakes and the ocean further downstream.…”

chirps: API Client for the CHIRPS Precipitation Data in R por Sousa, Kauê de, Sparks, Adam H., Ashmall, William, Etten, Jacob van, Solberg, Svein Ø.

“…The ESI data is based on satellite observations of land surface temperature, which are used to estimate water loss due to evapotranspiration (the sum of evaporation and plant transpiration from the Earth’s land and ocean surface to the atmosphere). The ESI data is available from 2001 to near-present. …”
