    String comment 
"The goal of this study is to document changes over time in ion and trace element aerosol concentrations at the Barrow Long Term Measurement Station.  The measurements began in 1997.  Funding for this project has come from NOAA, DOE, and beginning in 2002, NSF.

Sample Collection:
Submicron samples are collected on a 24-96 hour basis depending on season and aerosol loading. Supermicron samples are collected for 7 to 28 day periods, also depending on the season. The sample air volume minimum for analysis is 2.2 m^3.

The submicron - supermicron split is made with a Berner-type cascade impactor having a D50, aero of 1.0 um at the RH of the sample stream. Hence, the submicron data are for particle sizes < 1.0 um and supermicron data are for particle sizes > 1.0 um and < 10 um. The RH of the sampled aerosol is < 40%.

Ion Analysis:
All samples have been analyzed by ion chromatography for MSA-, Cl-, Br-, NO3-, SO4-2, oxalate, Na+, NH4+, K+, Mg2+, and Ca+2. Submicron samples are analyzed for total mass by gravimetric analysis at 55 +/- 5% RH. All ion and mass concentrations are given in ug/m3 at STP. More details of the sampling and IC and gravimetric analysis methods can be found in Quinn et al., J. Geophys. Res., 105, 6785 - 6805, 2000.

We define the limit of detection at the 95% (2-sigma) confidence level for ion chromatography to be consistent with the historical record at the Barrow Observatory. The final concentration has been adjusted by subtracting out the average annual blank value for each ion. Ion chromatography uncertainty was determined by triplicate analysis of a random sample. Annually averaged blanks, limit of detection (LOD: blank+2-sigma), and repetitive analysis uncertainty (1-sigma) are in ug/m3. The LOD for years prior to 2015 is based on the values presented in Quinn et al., J. Geophys. Res., 105, 6785 - 6805, 2000. After 2015, the blank and LOD values are calculated using the actual values collected during the year.

Trace Element Analysis:
Winter/Spring Barrow submicron samples were also analyzed by Xray fluorescence (XRF) for Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, As, Br, Sr, and Pb. Element concentrations are given in ug/m3 at STP. Uncertainty (1-sigma) for the XRF data is derived from four different effects (calibration, counting statistics, peak overlap correction, and absorption). It is listed for each sample in the file in ug/m3. The detection limit for XRF data is 3-sigma, in ug/m3. The final concentration has been adjusted to subtract out the average blank value for each element. The XRF filter area is 11.3 cm2. More details of the XRF analysis can be found in Buck, N.J., P.M. Barrett, P.L. Morton, W.M. Landing, and J.A. Resing, Energy dispersive X-ray fluorescence methodology and analysis of suspended particulate matter in seawater for trace element compositions and an intercomparison with high-resolution inductively coupled plasma-mass spectrometry. Limnol. Oceanogr. Methods, 19(6), 401-415, doi: 10.1002/lom3.10433, 2021.

Dataset Descriptors:
There are separate files for submicron and supermicron data.
The column names indicate the instrument used (IC or XRF), the element or ion measured, the size cut, and the measured concentration or blank concentration or uncertainty of the analysis.
Where values are absent, the following flags indicate:
1) V- missing volume or volume below 2.2 m^3,
2) BDL - below the detection limit listed,
3) M- missing/not analyzed.

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

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.
