Template for submission of Differential / Scanning Mobility Particle Sizer measurements - level 1

Points to note:

  • Reference pressure and temperature for concentrations:
    A level 1 file contains the data referenced to standard conditions of temperature and pressure (273.15 K, 1013.25 hPa).
  • Corrections applied:
    Level 1 DMPS/SMPS data contain inverted particle size distributions (particle concentration normalized to log10 width of size interval). This includes corrections with respect to equilibrium charging efficieny and multiply charged particles, counting efficiency function of the systems CPC, and diffusion losses in the inlet system.

Downloading template as text file

You could download the template and start to modify the text with your own metadata. Due to limitations of the online portal we could not provide files with the .nas file extension. So please download the text file and edit, and remember to use the .nas file-extension when you create your datafile: dmps_lev1.txt

Validation and submission:

To validate the file, please use the EBAS Submission Tool

Flags commonly used with this format:

All the flags defined for EBAS can be used, and the data submitter is encourage to go through the list of all EBAS flags prior to submitting to ensure that appropriate flagging is done.
Flags are grouped in four categories: V (valid measurement), I (invalid measurement), M (missing measurement) or H (hidden and invalid measurements)..
Apply '000' for valid measurements without any annotations.
The most common flags for these measurements are:

Group 9: Missing flags

FlagValidityDescription
999MMissing measurement, unspecified reason
980MMissing due to calibration or zero/span check

Group 6: Mechanical or instrumental problem

FlagValidityDescription
640VInstrument internal relative humidity above 40%

Group 5: Chemical problem

FlagValidityDescription
559VUnspecified contamination or local influence, but considered valid

Group 1: Exception flags for accepted, irregular data

FlagValidityDescription
110VEpisode data checked and accepted by data originator. Valid measurement

Group 0: Valid data

FlagValidityDescription
000Vvalid data, no flag

Template for Data Submission:

Clicking on a specific line in the example template will provide a detailed explanation and possible options for each of the metadata elements.

The example template given below contains the metadata fields that are commonly included when reporting data related to this specific template. Some of these metadata elements may not be relevant for your data reporting, like AIRS station ID for stations outside North America or the various QA measure data when there is no QA measure for the data. Such metadata elements could be let out. If you want to include additional metadata elements that are not given in the example template, there is a complete list here. In case of any doubt about such additional metadata, please consult the EBAS team!
