====== yyyy_ss.txt ======

These output files hold modelled annual load results. //yyyy// stands for a year during the simulation period and //ss// stands for one of the HYPE-modelled nitrogen (IN, ON) and phosphorus (PP, SP) species (an actual file name would be e.g. //2001_IN.txt//). The files contain modelled annual nutrient loads before and after retention/removal along the modelled nutrient transport pathways.

//yyyy_ss.txt// are tab-separated files written to the [[start:hype_file_reference:info.txt&#model_options|resultdir]] folder if requested in [[start:hype_file_reference:info.txt&#output_options|output options of info.txt]]. The first row contains a column header with variable names. The following rows contain values for all variables, in one row per sub-basin. 

The table below describes all variables written column-wise in //yyyy_ss.txt//. Variables with a //_nn// in header suffix are calculated for each SLC class separately, with //nn// numbers corresponding to numbers in [[start:hype_file_reference:geoclass.txt|GeoClass.txt]], so that the total number of columns varies depending on the number of SLC classes in the model set-up. Point source variable with a //NN// in header suffix are currently eight in total follow each other in order.
