    "Generalized country outlines and 0.1-degree climate cells omit some coasts and small islands.",
    "A destination pixel count is not an area total, population weight or national statistic; EPSG:3857 cells are not equal-area on the ground.",
    "The displayed climate class may differ from a nearby station's own monthly normals. Do not infer station observations from this raster.",
    "1991–2020 is a climatological period, not today's weather or a future projection.",
    "Country masks follow the site's source geometry; this is not an independent statement on disputed boundaries.",
    "Scope matches the existing Latin America atlas (34 countries/territories including PRI and FLK, excluding Mexico). French Guiana is not a separate feature in the site source geometry."
