When water droplets go from being present to not being present over the probe head there is a noticeable decay in the data which causes a exponential decay of sorts to be present. This then results in an indication that water droplets are supposed to be present even though there are no droplets passing over the probe head during this decay period of time. Attached below are photos and graphs that better visualize the problem that is present while using the WCM probe. | During the use of the WCM it was noticed that when compared to other instruments such as the Cloud Droplet Probe, RICE probe, and the hot wire boom probe there is a decay present after the water content should have gone to zero over the probe head. This is now something that is being lab tested to better understand what is going on with the probe and to try and correct this invalid data that is being collected. Below are references to where the data is located for this particular lab run. |
