Scale:

10 km/pix.

Map's precision:

The map contains precipitation totals for the period with stable temperature above 5° for patches of Earth's surface with the area 10 х 10 km. The layer is derivative and has been derived by way of calculation on the basis of mean monthly air temperature and mean monthly precipitation amount layers.

Main content:

A bitmapped map containing precipitation totals for the period with stable temperature above 5°.

Classifier precision:

Precipitation totals are expressed in mm.

Map compilation procedure:

The layer is derivative and has been derived by way of calculation on the basis of mean monthly air temperature and mean monthly precipitation amount layers (Afonin, A.N., Li, Y. S., Lipiyaynen, K.L., Tsepelev, V.Y., 2006). The calculation has been carried out by general method (Losev, A.P., 1994) in Idrisi program using macro-programming. "-100" - designation of pixels outside the Atlas.
