FLUID: Bio-optical water quality parameters (in-situ 2017-2019) in 4 Baltic lakes

The database consists bio-optical measurements done under FLUID¹ project in 4 different lakes (Burtnieks, Lubans, Razna and Võrtsjärv) during 2017-2019. The listed parameters are: LAKE (name) DATE TIME (local time) LAT (latitude) LON (longitude) Air T (air temperature in Celcius) Water T (water temperature in 0.5 m depth in Celcius) DO (dissolved oxygen in ppm) O2 (O2 saturation in %) Secchi (in meters) Chl a (chlorophyll-a in mg/m3) Pheo (pheopigments in mg/m3) TSS (total suspended sediments in mg/l) OSS (organinc suspended sediments in mg/l) MSS (mineral suspended sediments in mg/l) CDOM (absorption of coloured dissolved organic matter at 400 nm) TN (total nitrogen in mg/l) TP (total phosphorus in mg/l) CO2 (carbon dioxide in mg/l) ¹FLUID is funded by ERDF, Latvian state budget and IES proposal No.1.1.1.2/VIAA/1/16/137, Contract No. 1.1.1.2/16/I/001 “Innovative tool for lake monitoring using remote sensing data"
