WorldClim V1 Bioclim متغیرهای زیست اقلیمی را ارائه می دهد که از دما و بارندگی ماهانه مشتق شده اند تا مقادیر بیولوژیکی معنی داری بیشتری تولید کنند.
متغیرهای زیست اقلیم نشان دهنده روندهای سالانه (به عنوان مثال، میانگین دمای سالانه، بارش سالانه)، فصلی (به عنوان مثال، محدوده سالانه در دما و بارندگی)، و عوامل محیطی شدید یا محدود کننده (به عنوان مثال، دمای سردترین و گرم ترین ماه، و بارش فصل مرطوب و خشک) هستند.
طرح نوارها از ANUCLIM پیروی می کند، با این تفاوت که برای فصلی بودن دما از انحراف استاندارد استفاده شده است زیرا ضریب تغییرات در دماهای بین 1- و 1 معنی ندارد.

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.
