Calculating the Lifting Condensation Level (LCL)
This Javascript calculator was designed to calculate lifting condensation level (LCL) conditions using only three atmospheric input parameters that are commonly measured and reported during most local televised weather forecasts: surface temperature, surface dewpoint, and surface pressure. Output is pressure and parcel temperature at LCL. Though this calculator was designed to calculate the lifting condensation level for a parcel of air lifted from the surface, you calculate the LCL conditions for an air parcel at any other pressure level by substituting values appropriately. There is also a link to a calculator that will convert temperature reading from Celsius to Fahrenheit to Kelvin units.
