The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | SPLASH Field Study; NOAA GML Kettle Ponds Surface Radiation Budget and Near-Surface Meteorology Data (NCEI Accession 0302673) |
| Abstract: | These files contain Surface Energy Balance data at the Kettle Ponds (CKP) site as part of NOAA’s Global Monitoring Laboratory’s deployment in the Sail-SPLASH Campaign between October 2021 through August 2023. Disclaimer: The site was installed in October 2021, but was moved from the original place of installation ~100m east in September 2022. Due to prolonged periods of network outages, icing of the instruments and the accumulation of snow covering the instrumentation, some data may be “missing” for minutes, hours, days, and in rare cases, weeks. Filename information: RADSYS data files contain one day of data for one station. The naming convention for RADSYS data filenames is "stayyjjj.dat", where sta is a three-letter station identifier, yy represents the last two digits of the year (i.e., 95 for 1995, 00 for 2000), and jjj is the day of year. A "day of year" in a filename that is less than 100 would be preceded by one or two zeros, e.g., day 75 would appear as 075, day 2 would appear as 002 in the filename. The SURFRAD processing software is year 2000 compliant. The year within the data files is written unambiguously with 4 digits on each line. Station Identifier List: "ckp" is the station identifier for the Kettle Ponds site from the SPLASH field campaign in Crested Butte, Colorado. The extension ".dat" is used because both radiation and meteorological data are included. The file "ckp21289.dat" contains all of the radiation and meteorological data for Kettle Ponds on day 289 of 2021. Data Structure: RADSYS data are organized into daily files of one minute data, and are written in ASCII text. RADSYS data follows the quality control (QC) philosophy of the BSRN. Bad data are deleted, but questionable data are only flagged. Integer QC flags follow each data point. A QC flag of zero indicates that the corresponding data point is good, having passed all QC checks. A value greater than 0 indicates that the data failed one level of QC. For example, a QC value of 1 means that the recorded value is beyond a physically possible range, or it has been affected adversely in some manner to produce a knowingly bad value. A value of 2 indicates that the data value failed the second level QC check, indicating that the data value may be physically possible but should be used with scrutiny, and so on. Missing values are indicated by -9999.9 and should always have a QC flag of 1. The file structure includes two header records; the first has the name of the station, and the second gives the station's latitude, longitude, elevation above mean sea level in meters, and the version number of the file. These are followed by at most, 1440 lines of 1-min. data. Files are organized in Universal Coordinated Time (UTC). The date and time are given on every line. Data are reported as 1-minute averages of one-second samples. Reported times are the end times of the 1-min. averaging periods, i.e., the data given for 0000 UTC are averaged over the period from 2359 (or 2357) of the previous UTC day, to 0000 UTC. The solar zenith angle is reported in degrees on each line of data. It is computed for the central time of the averaging period of the sampled data. Missing-data periods within the files are not filled in with missing values, therefore, a file with missing periods will have fewer than 1440 lines. Radiation values are reported to the tenths place. Although this is beyond the accuracy of the instruments, data are reported in this manner in order to maintain the capability of backing out the raw voltages at the accuracy that they were originally reported. |
