String history
"Spectral reflectance was measured directly at the foliar (leaf) level in the field. Data acquisition was performed using a portable spectroradiometer PolyPen RP410 UVIS (spectral response range: 380-790 nm; PSI, Drásov, Czech Republic), ensuring non-destructive sampling while capturing the physiological status of the plants under natural ambient conditions

String summary "Reflectance measurements - CCT. This dataset contains spectral reflectance measurements collected in situ during the peak of the summer growing season (July) for Bistorta vivipara, Cassiope tetragona, Oxyria digyna, Saxifraga oppositifolia, Carex rupestris, Dryas octopetala, and Salix polaris. Reflectance data are fundamental for assessing the optical properties of the vegetation and deriving key spectral indices (e.g., Normalized Difference Vegetation Index (NDVI), PRI).";

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.
