====== Read SOURCES.DAT + Local Sources ======

Opens the Global Database [[sources database sources.dat|SOURCES.DAT]] and, if specified, the additional [[localdb|Local Database]]. \\
The maximum amount of sources is 150 in total (Global+Local Database).

===== Possible Problems & Solution =====

==== Cannot open the Database ====
Make sure that it exists and that it is readable.

==== ENVI-met does not read the Local Source Database ====
The [[[localdb]|Local Database]] will only be read if the [[sources database sources.dat|Global Database]] was opened successfully.

==== ENVI-met cannot identify the Source Type ====
The type of source is defined in the Main [[Configuration File]] in the [[[sources]|[SOURCES]-Section]], not in the Sources Database. \\
Normally, if no ''[SOURCES]-''Section is found but pollutants are used in the area, PM10 is the default pollutant. \\
If your ''[SOURCES]-''Section contains invalid data, ENVI-met will **disable** the sources!
