The Longley Rice Website
The well known algorithm for terrestial propagation analysis.
Here we are going look at who Longley and Rice were. Explain the propagation analysis algorithm and lead on to a dedicated terrestial propagation analysis website using the Longley Rice analysis.

Who
In reality Longley and Rice are two different people.
Anita Longley, Phil Rice, and their colleagues at the Central Radio Propagation Laboratory (CRPL) (now the Institute for Telecommunication Sciences (ITS)). In the 60's they developed an empirical model (based on electromagnetic theory) with measured data (terrain features and radio measurements) to create what is now known as the LongleyRice Irregular Terrain Model (ITM).
Anita Longley was born in the province of Saskatchewan, Canada 1908 and died in 1986. She received her BA in Physics from McMaster University and MS in Physiological Chemistry from the University of Minnesota. After serving as a research assistant and teaching at the high school and university, she joined the National Bureau of Standards (NBS) CRPL in Boulder, Colorado, in 1955.
Philip Rice was born Washington DC in 1922 and died 1997. He attended Lawrence College, Appleton, Wis., in 1941, and received the B.S. degree from the Principia College, Elsah, Ill., in 1948. Phil Rice specialized in mathematical modeling, tropospheric propagation, satellite and space communication. Since 1949 he was with CRPL Colorado.
