Hijmans, Susan Cameron,\nand Juan Parra, at the Museum of Vertebrate Zoology, University of\nCalifornia, Berkeley, in collaboration with Peter Jones and Andrew Jarvis\n(CIAT), and with Karen Richardson (Rainforest CRC).\n\n### Bands\n\n\n**Pixel Size**\n\n927.67 meters\n\n**Bands**\n\n| Name | Units | Min | Max | Scale | Pixel Size | Description |\n|---------|--------------------------|---------|----------|-------|------------|------------------------------------------------------------|\n| `bio01` | °C | -29\\* | 32\\* | 0.1 | meters | Annual mean temperature |\n| `bio02` | °C | 0.9\\* | 21.4\\* | 0.1 | meters | Mean diurnal range (mean of monthly (max temp - min temp)) |\n| `bio03` | % | 7\\* | 96\\* | | meters | Isothermality (bio02/bio07 \\* 100) |\n| `bio04` | °C | 0.62\\* | 227.21\\* | 0.01 | meters | Temperature seasonality (Standard deviation \\* 100) |\n| `bio05` | °C | -9.6\\* | 49\\* | 0.1 | meters | Max temperature of warmest month |\n| `bio06` | °C | -57.3\\* | 25.8\\* | 0.1 | meters | Min temperature of coldest month |\n| `bio07` | °C | 5.3\\* | 72.5\\* | 0.1 | meters | Temperature annual range (bio05-bio06) |\n| `bio08` | °C | -28.5\\* | 37.8\\* | 0.1 | meters | Mean temperature of wettest quarter |\n| `bio09` | °C | -52.1\\* | 36.6\\* | 0.1 | meters | Mean temperature of driest quarter |\n| `bio10` | °C | -14.3\\* | 38.3\\* | 0.1 | meters | Mean temperature of warmest quarter |\n| `bio11` | °C | -52.1\\* | 28.9\\* | 0.1 | meters | Mean temperature of coldest quarter |\n| `bio12` | mm | 0\\* | 11401\\* | | meters | Annual precipitation |\n| `bio13` | mm | 0\\* | 2949\\* | | meters | Precipitation of wettest month |\n| `bio14` | mm | 0\\* | 752\\* | | meters | Precipitation of driest month |\n| `bio15` | Coefficient of Variation | 0\\* | 265\\* | | meters | Precipitation seasonality |\n| `bio16` | mm | 0\\* | 8019\\* | | meters | Precipitation of wettest quarter |\n| `bio17` | mm | 0\\* | 2495\\* | | meters | Precipitation of driest quarter |\n| `bio18` | mm | 0\\* | 6090\\* | | meters | Precipitation of warmest quarter |\n| `bio19` | mm | 0\\* | 5162\\* | | meters | Precipitation of coldest quarter |\n\n\\* estimated min or max value\n\n### Terms of Use\n\n**Terms of Use**\n\n[CC-BY-SA-4.0](https://spdx.org/licenses/CC-BY-SA-4.0.html)\n\n### Citations\n\nCitations:\n\n- Hijmans, R.J., S.E.
