String summary "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 degrees of latitude and 125 degrees 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).";

Data Access Protocol (DAP) and its
selection constraints.
The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.
Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names,
followed by a collection of
constraints (e.g., variable<value),
each preceded by '&' (which is interpreted as "AND").
For details, see the tabledap Documentation.
