attribute	NC_GLOBAL	summary	String	These data derive from an international sampling programme aimed at ascertaining the extent of diel variation in CO2 flux (FCO2) across multiple lakes. Sampling took place at 21 lakes, spanning 89° of latitude and 125° of longitude. Some lakes were sampled more than once, so the dataset comprises 41 sampling campaigns measuring FCO2 at circa 4-hour intervals over a full diel (24 hour) cycle. Floating chambers with in-situ CO2 sensors was deployed between November 2016 and October 2018. Rates of FCO2 ranged from -3.16 to 4.39 mmol m-2h-1. In addition to FCO2, this dataset contains lake and campaign metadata, including water temperatures and pCO2 of the surface water, meteorological data for each campaign from the nearest weather station and the calculated mixing depth (Zmix) and turbulent velocity scales for wind shear (u*) and convection (w*). This work is the result of an international team science effort facilitated by the Global Lake Ecological Observatory Network (GLEON). A paper describing these data in more detail, and the analysis of the results is in preparation (de Eyto et al in prep).
