After requesting O2A-SENSOR for observation properties, the O2A-INGEST performs the following tests.
Test | Description | Property* | Ancillary data* | Status |
---|---|---|---|---|
Operation temperature range | Test for temperature conditions (air and/or surface temperature) under which the instrumentation is deployed. | Operation Temperature | Temperature observation | operational |
Manufacturer range | Test if the value is within the limits of the instrumentation (e.g. due to construction, material, or filter) given by the manufacturer. | Manufacturer range | None | operational |
Operation range | Test if the value is within a specific range valid for the location where the sensor is deployed. | Operation range | None | operational |
Gradient test | Test for gradient, i.e. absolute distance from the median value of neighboring (n=5) observations. | Gradient Threshold | None | operational |
Spike test | Test for spikes, i.e., distance from the median value subtracted by the standard deviation of neighboring (n=5) observations. | Spike Threshold | None | operational |
Range function | Test for physical relationships, or interdependency, among observations. | Thresholds array | None | development |
Geolocation | Test for a valid geographic location of moving and stationary sensors. | Latitude, longitude and altitude ranges | Location of observations or Event ("Mount", "Deployment", or "Information") | development |
*These parameters are required to perform the test.
