&r solradb <trn> <lps> <dem> <out> <lat> <time> <base> <days> <sel>
where: trn = file name for transmittance data; lps
= file name for lapse rate data; dem = file name of DEM; out
= base name of outgrid file names (w|out index); lat = latitude
of study site (DEM); time = daily time interval for solar pass (in
minutes); base = base elevation for transmittance data; days
= # of days the lapse rate data are averaged for; sel = method
for transmittance (where: 1= maximum transmittance per period; 2 = horizontal
radiation based transmittance; 3 = direct radiation based transmittance;
4 = corrected direct radiation based transmittance).
All the other requirements are the same meaning that for running the
solradb.aml two files containing transmittance and lapse rate data have
to be prepared prior to running the AML. The AML automatically runs the
two additional command procedures rdtrans.aml
and rdlpsrt.aml. So you have to download
those as well!
| Command: | &r solrad <parameters> (at GRID or ARC prompt) |
