Basin properties: Knoben climate indicators

The climate indicators are based on Knoben et al. (2018). The climate indicators aridity I_m, seasonality I_m,r, and precipitation as snow f_S are estimated using daily precipitation, avergage daily temperature, and potential evapotranspiration of the watershed. The three indicators are used to derive a color which is used to identify the continuous climatic zones.

The indicators have the following ranges:

• aridity (arid to wet) [-1,1]
• seasonality (constant to seasonal) [0,2], and
• precipitation as snow (no snow to all snow) [0,1]

The RGB color derived from these indicators is defined as follows:

• aridity (red)
• seasonality (green), and
• precipitation as snow (blue)

The following map allows you to display the three climate indicators as well as the color proposed by Knoben et al. (2018) that is indicating the climatic zone (Fig. 2 in Knoben et al. (2018)).
