The ClimateBasis programme gathers and accumulates data describing the climatological and hydrological conditions in Kobbefjord. Data are measured by two automatic climate stations (C1 and C2), two automatic hydrometric stations (H1 and H2) and three diver stations (H3, H4 and H5).

The two climate stations are placed next to each other to ensure data continuity. Sixteen climate parameters are monitored and data, including two derived parameters, are stored in the database.

The mean annual air temperature in 2010 was 3.4 °C, which is the highest annual air temperature measured in Kobbefjord since the start of the programme. In addition, the frost free period lasted longer than in previous years with the first day with a mean air temperature above freezing occurring 16 days earlier than in 2008/2009 and the last day with a mean air temperature above freezing occurring 31 days later than in 2007-2009.

In Kobbefjord, measurement of the water level and discharge started in 2006 at H1, at H2, H3 and H4 in 2007, and at H5 in 2008. Manual measurements of discharge were in 2010 continued at H1, H3, H4 and H5. H1 and H2 are measuring throughout the year, while measurements at H3, H4 and H5 starts up in early spring when the rivers are free of snow and ice, and ends in late fall before the river freezes.

In 2009, a final Q/h-relation was established, incorporating discharge measurements over nearly the entire recorded water level. For H2, H3, H4 and H5 there still is a lack of discharge measurements at high water levels to establish reliable Q/h relations.

For H1, which is placed at the main river in Kobbefjord, the total discharge during the hydrological year 2009/2010 was 22.9 million m³. The peak discharge in 2010 was recorded 30 August and was caused by a rain event.
