Dew Point (DewPt)
Inputs
temperature

Outputs
dew point
Description
This block computes dew point from temperature and humidity. The temperature input may have
units of either Celsius or Fahrenheit (the units field of the incoming data is used to determine
which is in effect). The humidity input is expected to be a percentage.
The dew point output is expressed in the same units as the incoming temperature.
The block has no user-set properties. Dew point is computed according to the “WMO Guide to
Meteorological Instruments and Methods Observation” WMO-No.8 seventh edition, 2006.
Block Placement
The Dew Point block should typically come BEFORE the measure (or average, or other “active”
block) that executes it. This ensures the block operates on data from the same measurement
frame, and avoids odd side effects that come from active blocks operating on split paths.
