Fixes backtracking and modifies dry deposition

Main changes included:

1. Final fixes to collecting EC metrology files
2. Fixes problems in backtracking module which arose due to the new collection of data.
3. Modifies viscosity in dry deposition modules to be dependent on temperature (and therefore consistent with gravitational settling)
