Budyko Index
Budyko Index is based on characteristics of the surface heat and water balance.
bi(data, pr, data_names = NULL, na.rm = FALSE, ...)
data |
net radiation, J/m2 |
pr |
daily precipitation, mm |
data_names |
names of each period of time |
na.rm |
logical. Should missing values (including NaN) be removed? |

index value
BI = 100\frac {Rn}{L*P}
Rn= annual net radiation, P = annual precipitation, L = latent heat of vaporization for water
