Database of Agroclimatic Indices in Honduras (1981-2022): Historical Record of Dry Conditions, Heatwaves, and Water Availability Across Agricultural Seasons.

The dataset consists of spatial information with a grid resolution of 0.05°, providing historical agroclimatic indices related to dry conditions, extreme heat, and water availability during the agricultural seasons (Primera, Canícula, Postrera, and Apante) in Honduras. Spanning from 1981 to 2022, it includes eight indices categorized into Dry Conditions (Number of Dry Days, Number of Dry Spells, Average Length of Dry Spells),

Extreme Heat (Number of Heat Days, Number of Heat Nights), and Water Availability (Potential Evapotranspiration, Total Precipitation, Standardized Precipitation and Evapotranspiration Index). To elucidate the impact of climate variability, the dataset considers eight El Niño events (1982, 1987, 1991, 1997, 1998, 2002, 2009, 2015) and seven La Niña events (1988, 1999, 2000, 2007, 2011, 2021, 2022). These events provide a framework for characterizing how each agroclimatic indicator responds under the influence of different phases of the El Niño–Southern Oscillation (ENSO) phenomenon, offering valuable insights for understanding and adapting to climate variations in the agricultural context.
