## Data level
The processed PyrNet data is structured in data levels.
Starting from the raw (logger) data in ASCII fromat, the processed data is stored in netCDF4 files

```{list-table} PyrNet data level
:header-rows: 1
:name: tab-datalvl

* - Level
  - Description

  - Meta data
* - l1a
  - Maintenance period data; Uncalibrated raw readings from logger
  - Full time resolution (10Hz ADC, 1Hz GPS) 
  - Maintenance quality flags; Campaign meta data
