NORTRIP model text parameter file (activities)
----------------------------------------------
SALT AND SAND RULES 0 Keep this line and number here
Salting Value Comment
salting_hour(1) (hour) 5 First time of day when salting can occur
salting_hour(2) (hour) 17 Second time of day when salting can occur
delay_salting_day (day) 0.45 Minimum allowable time between salting events in days
check_salting_day (day) 0.5 Time window checked ahead (temperature, RH) and behind (precip)
min_temp_salt (C) -10 Minimum temperature for salting in the forward time window
max_temp_salt (C) -1 Maximum temperature for salting in the forward time window
precip_rule_salt (mm/hr) 0.3 Salt if precipitation occurs above this level in the forward and behind time window or RH_rule
RH_rule_salt (%) 95 Salt if the relative humidity is above this level in the forward time window or precip rule Changed from
g_salting_rule (mm) 0.2 Dry salt if the surface moisture is above this value at time of salting
salt_mass (g/m2) 10 Mass of salt applied at each application
salt_dilution 0.2 Salt solution, if 0 then always dry salting
salt_type_distribution 1.0 M(salt) = M(salt1)*salt_type + M(salt2)*(1-salt_type) ; Salt 1=NaCl
Sanding Value Comment
sanding_hour(1) (hour) 7 First time of day when sanding can occur
sanding_hour(2) (hour) 7 Second time of day when sanding can occur
delay_sanding_day (day) 5 Minimum allowable time between sanding events in days
check_sanding_day (day) 0.5 Time window checked ahead (temperature, RH) and behind (precip)
min_temp_sand (C) -50 Minimum temperature for sanding in the forward time window
max_temp_sand (C) -5 Maximum temperature for sanding in the forward time window
precip_rule_sand (mm/hr) 0.3 Sand if precipitation occurs above this level in the forward and behind time window or RH_rule
RH_rule_sand(%) 0 Sand if the relative humidity is above this level in the forward time window or precip_rule
g_sanding_rule (mm) 0.5 Sand if the surface moisture (snow or ice) is above this value at time of sanding
sand_mass (g/m2) 2000 Total mass of sand applied at each application (x 10 because it is scaled down by 10 in the flags. This allows for the Trondheim activity data to be scaled down)
sand_dilution 0 Sand in solution, if 0 then always dry sanding
Snow ploughing Value Comment
delay_ploughing_hour (hr) 3 Minimum time between between snow ploughing events
ploughing_thresh (mm) Overrides existing parameter, threshold at which ploughing occurs, set in Parameter table.
Road cleaning Value Comment
cleaning_hour(1) (hour) 4 First time of day when cleaning can occur
cleaning_hour(2) (hour) 16 Second time of day when cleaning can occur
delay_cleaning_day (day) 14 Minimum time between between cleaning events (days)
min_temp_cleaning (C) 0 Minimum temperature at which cleaning can occur
start_month_cleaning (MM_num) 11 Month number after which cleaning can occur
end_month_cleaning (MM_num) 4 Month number after which no cleaning can occur
clean_with_salting 0 Sets the cleaning event to occurr during a salting event. Temperatures must be compatable
wetting_with_cleaning (mm) 0.6 Include wetting with the cleaning (mm or litre/m2)
efficiency_of_cleaning 1.0 Relative efficiency of the auto cleaning, compared to h_cleaning-eff
Dust binding Value Comment (type of binder specified in the header of the activity input file sheet)
binding_hour(1) (hour) 5 First time of day when binding can occur
binding_hour(2) (hour) 17 Second time of day when binding can occur
delay_binding_day (day) 4 Minimum allowable time between binding events in days
check_binding_day (day) 0.5 Time window checked ahead (temperature, RH) and behind (precip)
min_temp_binding (C) -50 Minimum temperature for binding in the forward time window
max_temp_binding (C) 25 Maximum temperature for binding in the forward time window
precip_rule_binding (mm/hr) 0.2 Do not bind if precipitation occurs above this level in the forward or backward time window
RH_rule_binding (%) 40 Bind if the relative humidity is above this level anywhere in the forward time window
g_binding_rule (mm) 0.05 Bind if the surface moisture is currently below this value
binding_mass (g/m2) 2.5 Mass of binding applied at each application
binding_dilution 0.2 Binding solution in mass, if 0 then dry
start_month_binding (MM_num) 11 Month number after which binding can occur
end_month_binding (MM_num) 4 Month number after which no binding can occur
