30-seconds (1 Km2) gridded Future Climate Change Scenarios for Honduras

Future climate change scenarios for Honduras were developed by downscaling CMIP5 projections from 18 General Circulation Models (GCMs) for four Representative Concentration Pathways (RCP’s; RCP 2.6, 4.5, 6.0, and 8.5; IPCC, 2013) and three future periods named as 2030s (Climatic normal –CN- for 2021 to 2050), 2050s (CN for 2041-2070) and 2080s (CN for 2071 to 2100).

The future periods were selected by PNUD and MiAmbiente in Honduras in order to get climatic information for the decision making processes around the climate change in the short, medium and large terms. We follow the delta method downscaling described in Ramírez-Villegas and Jarvis (2010). We developed surfaces at 30-seconds (1 Km2) of spatial resolution, for monthly precipitation (prec), monthly minimum temperature (tmin), maximum temperature (tmax), mean temperature (tmean), diurnal temperature range (dtr), solar radiation (rsds) and wind speed mean (wsmean).

We make available three types of data:

<br>
<br>

<ul>
<li> Downscaled future scenarios for Honduras for each of the 18 GCM. </li>
<li> Downscaled future scenarios for Honduras for the ensemble (average) of all GCM. </li>
<li> Anomalies or climatic changes for future for Honduras for an ensemble (average) of all GCMs available. </li>
</ul>

The data is part of work carried out by CIAT in the generation of the climate change scenarios for Honduras for the Third National Communication to the UNFCCC.
