String summary "This dataset encompasses the detection of red fluorescent microspheres (uvpms_by) within the size range of 48-51 µm. The detection and analysis of the red fluorescence signal were conducted using microplastic detector photodiode (PD) channels 4, 5, and 6, each equipped with red fluorescence filters. These photodiodes have different signal gains, facilitating a broader dynamic range of detection. The timetrace data of the PD signals were captured and subsequently filtered using a low-pass filter. The timetrace data exhibited peaks corresponding to the presence of red microplastic particles in the measured sample. A peak-finding algorithm was employed to identify all peaks within the data. The dataset includes consecutive event numbers, representing peaks identified across all target channels (4, 5, and 6). Events detected in only a subset of these channels were excluded from the dataset. For each event, the amplitude (measured in the ADC sample range of 0-4095) and the width (measured in the number of samples) of the peak are reported. This dataset provides detailed information on the peak height and width for every event detected across all three channels, offering valuable insights into the detection capabilities of the microplastic detector.";

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.
