Data Submittion Guideline (1/2)

AsiaFlux Steering Committee welcomes your submission of your variable data sets to AsiaFlux database (AsiaFluxDB). The committee is open and receptive to diverse terrestrial ecosystem data sets at various time steps. One of the most important requirements for data submission is to prepare not only a data file itself but also two document files, site information file and data description file. The document file describes general information of your site, methodologies and noteworthy points/events on the use of your data. A packaged set of your original data and document files will be provided to AsiaFluxDB users. Your document file will prevent your variable data from inadequate and unintended usage or reading by AsiaFluxDB users.

AsiaFlux Steering Committee proposes data and document file formats outlined below in consideration of compatibility with some precedent similar databases and efficiency of data managements in AsiaFluxDB. AsiaFlux committee asks for your kind understanding.

Data sets should be emaild to AsiaFluxDB manager (asiafluxdbasiaflux.net).

1. Data File

  1. As a general rule, data file should be assembled per year.
  2. Observation data recorded different time step can not be mixed in one data file. For example, if you plan to provide both half hourly flux data and daily data such as precipitation and snow depth, please make two data files according to the time steps of your data. The two data files are identified by each specified file name (See 3. File Name).
  3. Gap-filled complete data and statistics (i.e. daily mean or annual sum) based on the gap-filled data should be separate from observed data file. Careful explanations about the applied gap-filling method are required in the document file for gap-filled data set.
** Please refer File Templates for a data sample.

2. Document Files

  1. General information of your site, methodologies and noteworthy points/events on the use of your data should be summarized in the document files (see 3. File Format)
  2. Each of your yearly data file will be packaged with the document files for the relevant data file.
  3. Entries of the document file (to the extent possible)
    • location of your site (latitude, longitude, elevation), time deference from UT
    • dominant vegetation, soil type
    • observation items, observation heights, methods, instruments
    • vegetation height, zero-plane displacement, roughness length
    • list of registered data, unit
    • methods of data quality control and assurance (QC/QA) and gap-filling
    • noteworthy points/events on the use of the data
    • creation date and update history information of each data file
    • principal investigator (PI) and contact person
    • other reference information (Web sites or published paper etc.)
** Please refer File Templates for file templates and samples.
