5.2 Meteorological information
Daily air temperature and humidity, precipitation totals from
meteorological stations of hydrometeorological network within or nearby
the basin were used as meteorological input for hydrological modelling.
Four of them, Suntar-Khayata, Nizhnyaya Baza, Vostochnaya and Agayakan,
were used for the period 1957-1964 and two, Agayakan and Vostochnaya,
for the period 1966-2012 (Table 3, Fig. 1). Input data from
meteorological stations are interpolated to each RP. The interpolation
is based on the triangulation method, when ideally each RP is inside a
triangle, in the corners of which there are weather stations. Linear
interpolation is conducted between the stations, if only two are
available.
