This model provides the global electron temperature between 300 km and 700 km altitude for two local times (3 a.m. and 3 p.m.). It is based on data collected by the AEROS retarding potential analyzer through the first 100 days in 1973. Spherical harmonics up to degree and order 3 are used to describe the electron temperature as a function of geomagnetic latitude and longitude. Altitude variations are represented by a power series of degree 3. Two sets of the 36 coefficients each are listed, one for 3 p.m. and one for 3 a.m..
