Level 1 Data#

exportdata_cn#

The *cn.txt files contain 3-second-binned data:

  • time relative to start of run

  • particle concentration

  • particle count

  • INP concentration

  • INP count

  • run mode: flush (1), expansion (2), refill (3)

  • mean flow rate

  • mean dew point temperature

  • mean chamber pressure

  • mean Ti1-Ti5

  • particle counts per size bin
    One file contains the data of one run.

exportdata_ice#

The *ice.txt files contain the run-wise data:

  • run ID

  • time at the middle of the flush

  • chamber number (only relevant for PINEair)

  • minimal temperature (Ti5) reached during expansion

  • pressure at the end of expansion

  • mean flow rate during expansion

  • INP count during expansion

  • INP concentration during expansion

  • INP concentration during flush

  • particle concentration during expansion

  • particle concentration during flush
    One file contains the data of one operation.

ice_threshold#

The *ice_threshold.txt files contain the bin number and the ice threshold for each run. The bin number does not correspond to the OPC bins, but follows a logarithmic equally sized distribution between 0.1 and 1000 \(\mu\)m. One file contains the data of one operation.
