FERNANDEZ EGUIARTE, Agustín; ROMERO CENTENO, Rosario  e  ZAVALA HIDALGO, Jorge. Methodologies used in the digital climatic atlas of Mexico for generating high-resolution maps. Geoacta [online]. 2014, vol.39, n.1, pp.165-173. ISSN 1852-7744.

The methodologies used to generate the monthly, high spatial resolution (926 m) climate maps that are incorporated into the Digital Climatic Atlas of Mexico (abbreviated to ACDM in Spanish) are described. These include the processing of data from more than 5200 weather stations feeding the daily climatological database of the Mexican National Weather Service covering the period 1902-2011 together with data covering the period 1950-2000 from the WorldClim-Global Climate Database. The procedures developed to perform data quality control and to structure geo-referenced databases of climate variables, as well as the validation processes and the establishment of metadata and data visualization through cartographic compositions, are explained. The climatic variables included are: temperature, precipitation, absolute extreme values, bioclimatic parameters, and meteorological drought.

Palavras-chave : Climatic cartography; Climatic variables; Extreme climatology; Meteorological drought; Bioclimatic parameters.
