Supporting data of the paper "In-lake GHG production constrained by lake DOM mass balance in a boreal catchment"

*This dataset is served as the supplementary data for the reviewing paper "In-lake GHG production constrained by lake DOM mass balance in a boreal catchment".This dataset provided the meteorology, hydrology, and water chemistry data of lake Langtjern (Norway) in 2023. The meteorology data includes daily wind speed (2m height), daily air temperature, and daily precipitation data, which were collected by the high-frequency sensor around the lakeshore in 2023.Hydrology data includes the daily catchment discharge into the lake, and the daily lake discharge output in 2023. The lake discharge output is downloaded from NVE (OA), and the ctachment discharge input is derived from the lake discharge output with using BV-model (an experienced hydrology model developed in lake Langtjern). The water chemistry data includes conductivity, pH, total nitrogen, dissolved organic carbon, dissolved gases (CO2 and CH4), total phosphrous, dissolved organic nitrogen, etc, from the grabbed samples in stream inlets, inner lake (littoral zone and central lake), and outlet. All chemistry data are measured by the professional commercial lab (NIVA), except for the dissolved gases (measured by myself).
