[TRNSYS-users] Ground Temperature parameters

[Diego A. Arias]

Dear Krishna,

The ASHRAE Handbook, in the Applications Volume, Chapter 31 - Geothermal 
Energy, lists thermal properties of different kinds of soils (density, 
thermal conductivity and thermal diffusivity). 
However, the data for mean surface temperature and amplitude of 
temperature variation must come from local measurements. The paper 
written by T. Kusuda and P.R. Achenbach (*) lists this information for 
many stations in the US.  I will appreciate if anyone else in this 
mailing list knows of additional databases for other countries.
Best regards,

Diego

Diffusivity at Selected Stations in the United States. ASHRAE 
Transactions, Volume 71, Part I, 1965.
