Bioclimatic parameter | Definition |
|---|---|
1. Annual mean temperature (AMT) | The mean of all monthly mean temperatures. |
2. Mean diurnal range (MDR) | The mean of all monthly diurnal temperature ranges which is the difference between the monthly maximum and minimum temperature. |
3. Isothermality (ISO) | MDR (parameter 2) divided by ATR (parameter 7) |
4. Temperature seasonality (TSCV) | Coefficient of variation of temperature expressed as a percentage. |
5. Max temperature of warmest period (TWP) | The highest monthly temperature. |
6. Min temperature of coldest period (TCP) | The lowest monthly temperature. |
7. Temperature annual range (TAR) | The difference between the TWP (parameter 5) and the TCP (parameter 6). |
8. Mean temperature of wettest quarter (TWetQ) | Mean temperature of the wettest quarter. |
9. Mean temperature of driest quarter (TDQ) | Mean temperature of the driest quarter. |
10. Mean temperature of warmest quarter (TWarmQ) | Mean temperature of the warmest quarter. |
11. Mean temperature of coldest quarter (TCQ) | Mean temperature of the coldest quarter. |
12. Annual precipitation (AP) | The sum of monthly precipitation within a year. |
13. Precipitation of wettest period (PWP) | The highest monthly precipitation. |
14. Precipitation of driest period (PDP) | The lowest monthly precipitation. |
15. Precipitation seasonality (PSCV) | Coefficient of variation of precipitation monthly precipitation expressed a percentage. |
16. Precipitation of wettest quarter (PWetQ) | Total precipitation of the wettest quarter. |
17. Precipitation of driest quarter (PDQ) | Total precipitation of the driest quarter. |
18. Precipitation of warmest quarter (PWarmQ) | Total precipitation of the warmest quarter. |
19. Precipitation of coldest quarter (PCQ) | Total precipitation of the coldest quarter. |
