The export files contain a large amount of detailed information collected from your sensors. At first use, reading them may seem complex.
The purpose of this article is to help you easily interpret your exports and identify the key metrics for monitoring your fields in the My Organization Data Export interface.
Export format and structure
Exports are available in CSV or XLSX format (encoded in UTF-8).
They are generated per field: depending on the amount of historical data, one field may produce one or several files.
The files are sent by email in .zip format; the download link is valid for 72 hours.
Inside the files:
- Each column corresponds to a distinct metric (temperature, rainfall, humidity, etc.).
- In some cases, a column represents a specific sensor (e.g. several tensiometers at the same depth).
- Each row corresponds to a moment in time, defined by the time step chosen during export.

Metrics and nature of the data
Exports contain a list of generic metrics specific to Weenat. Their availability depends on the type of sensors installed, the configuration of your fields, and the correct association between sensors and fields.
The nature of each data point may vary across several dimensions:
- By origin: the same metric may come from different sources.
- Example: humidity can be measured by a weather station, a thermometer-hygrometer, or come from Meteo Vision.
- By duration: the same field may have had several pieces of equipment over time.
- Example: an initial weather station replaced a few years later, or a change of tensiometers.
- By type: a metric can be either from a direct measurement or a calculation.
- Example: your data may come from your weather station, then from Meteo Vision if you remove the station.
In case of interruption (fallen sensor, discharged battery, breakdown…), moments without data appear as empty cells.
Each export includes a tab or a table that summarizes the meaning of the metrics.
Time step and covered period
When generating, you select a time step: hourly, daily, monthly, or yearly.
The period is defined in days: even for an hourly export, the data covers from midnight to midnight.
The generation time depends on:
- the number of fields exported,
- the length of the period,
- the chosen time step,
- and the number of included metrics.
This generation time is not included in the 72-hour validity of the download link.
