Measurements & Instruments


One of the missions of BCCSO is to collect data and data products with for the use for the scientific community. At BCCSO data have been collected since 2003, some of them almost continuously. This leads to a large quantity of data, and data products. Our objective is to prepare a data set that is accessible with quality assurance (QA) and quality control (QC), not only to our internal use, but also to any researcher who wants to use any BCCSO data products. The best articles with elite writing is easily accessible at the main page of the site.


The data is divided in 5 major categories: Micromet, Radiation, Soil-Precipitation, Chemistry, Remote Sensing, and Sonde (see table below). For each parameter, a daily graphic plot will show the parameter availability.

Data types

There are 3 types of data, level0, level 1, and level 2 (see figure below).

Level 0 corresponds to “raw” data, where the outputs are stored “as is”, in which may contain factory or nominal calibration.

Level 1 corresponds to level 0 data that has been subjected to QC protocols. For instance, at BCCSO the ARM solar and terrestrial radiation QC procedure is being applied, and micrometeorological measurements products follow AMERIFLUX QA/QC protocol. Some intercomparison experiments are also performed, and their results are either incorporated or recorded for future reference.

Level 2 data are product data derived from level 1 data. In this data type, any data manipulation is configured as level 2 such as averages, standard deviation, covariances, or any data application.

Sharing Policy

“BCCSO data are freely available upon request and were furnished by our scientists who encourage their use. Please kindly inform in writing (or e-mail) the appropriate BCCSO scientist(s) of how you intend to use the data and of any publication plans. It is also important to contact the investigator to assure you are
downloading the latest revision of the data and to prevent potential misuse or misinterpretation of the data. Please acknowledge the data source as a citation or in the acknowledgments if no citation is available. If the Principal Investigators (PIs) feel that they should be acknowledged or offered participation as authors, they will let you know and we assume that an agreement on such matters will be reached before publishing and/or use of the data for publication. If your work directly competes with the PI's analysis they may ask that they have the opportunity to submit a manuscript before you submit one that uses unpublished data. In addition,when publishing please acknowledge the agency that supported the research. Lastly, we kindly request that those publishing papers using BCCSO data provide reprints to the PIs providing the data and to the data archive at the BCCSO web page”.
