    126 - [NOT solved] PLACEHOLDER JAMES - problems with snow_frac 
     126- [NOT solved] problems with 'snow_frac', feeding into values for the snow albedo greater than 1, and crashes shortly afterwards  
     127 
     128- Variable that is causing the problem appears to be 'frac_snow_veg',  in the subroutine 'albedo_two_stream'. This is a variable that is calculated in 'calculate_snow_albedo' subroutine and passed up to 'albedo_two_stream', and from there to condveg. The only place that it is calculated is 'calculate_snow_albedo'. 
     129 
     130- In this particular model run it is zero for all PFTs. However in a later loop over all PFTs (within 'albedo_two_stream') the value of 'frac_snow_veg' strangely deviates from zero, which causes incremental  increases in the albedo, until eventually the model crashes. When I define a local variable for this PFT loop, 'frac_snow_veg_loc' (just within 'albedo_two_stream') the model does not crash. This is rather a clumsy solution, but it is strange that 'frac_snow_veg' does not retain its value during the loop.
