11. Compare the thickness map from Question 10 to the Mesonet surface temperature map. Focus on the placement of the freezing line at the surface. Both of these products were valid at 6:00 pm
- Do the two products place the freezing line in the same place?
- Which should you believe? Why?
Answer.
- The Mesonet freezing line is located about 100 miles south of the model output estimate.
- The model output is an estimate, based on equations, and is only updated every hour.
- The Mesonet line is based on actual data measured by quality-calibrated instruments, and it is updated every five minutes.
- Trust the Mesonet data!
The Bottom Line.
-
When it comes to surface conditions, you can't beat the timely, high-quaility data from the Oklahoma Mesonet.
