Abstract
Abstract. In 2018, 70 years have passed since the beginning of observations at the Kolyma Water-Balance Station (KWBS), a unique scientific research hydrological and permafrost catchment. The volume and duration (50 continuous years) of hydrometeorological standard and experimental data, characterizing the natural conditions and processes occurring in mountainous permafrost conditions, significantly exceed any counterparts elsewhere in the world. The data are representative of mountainous territory of the North-East of Russia. In 1997, the station was terminated, thereby leaving Russia without operating research watersheds in the permafrost zone. This paper describes the dataset containing the series of daily runoff from 10 watersheds with an area from 0.27 to 21.3 km2, precipitation, meteorological observations, evaporation from soil and snow, snow surveys, soil thaw and freeze depths, and soil temperature for the period 1948–1997. It also highlights the main historical stages of the station's existence, its work and scientific significance, and outlines the prospects for its future, where the Kolyma Water-Balance Station could be restored to the status of a scientific research watershed and become a valuable international centre for hydrological research in permafrost. The data are available at https://doi.org/10.1594/PANGAEA.881731.
Highlights
In 2018 we celebrate 70 years since observations at the Kolyma Water-Balance Station (KWBS) began
Nowadays only standard observations are conducted at the Nizhnyaya meteorological site and at the Kontaktovy (Nizhny) runoff gauge
We present a hydrometeorological and permafrost-related dataset for 50 continuous years from 1948 to 1997 for the KWBS, the Kontaktovy creek watershed, which is representative of vast mountainous territories of the continuous permafrost zone of Eastern Siberia and the northeast of Russia
Summary
In 2018 we celebrate 70 years since observations at the Kolyma Water-Balance Station (KWBS) began This hydrological and permafrost research catchment has accumulated standard and experimental data unique in terms of both their amount and duration. We present a hydrometeorological and permafrost-related dataset for 50 continuous years from 1948 to 1997 for the KWBS, the Kontaktovy creek watershed, which is representative of vast mountainous territories of the continuous permafrost zone of Eastern Siberia and the northeast of Russia This dataset is unique in terms of its volume and duration of hydrometeorological standard and experimental data. It may be used in many research tasks, but is of particular importance in studying runoff formation processes and model development in permafrost regions
