Abstract

GH Gage height in millimeters of antifreeze-water solution in the collection tank. GH(Measured initial height in millimeters of antifreeze in the collection tank after emptying and recharging. GPC Measured distance in millimeters from the lower fixed reference pen trace to the precipitation pen trace. GPT Measured distance in millimeters from the instrument reference point to the precipitation pen in lap no. 1, measured during service visits. GVT Measured height in millimeters of the antifreeze-water solution in the gage collection tank, measured during service visits. kg/L Kilograms per liter. Lc Chart "lap" correction if lap no. is greater than 1. Lap no. and pen position are determined from chart measurements when the chart is analyzed. LPT Average of the measurements in millimeters made at the beginning and end of each chart from the instrument reference point to the lower fixed pen, measured during service visits. LUC Measured distance in millimeters from the lower fixed pen trace to the upper fixed pen trace. P Daily precipitation catch in millimeters. PM Total depth in millimeters of antifreeze-water solution in the gage collection tank on a given day. PM_2 Previous day's maximum depth in millimeters of antifreeze-water solution in the gage collection tank. T Daily average air temperature in degrees Celsius. T0 Temperature in degrees Celsius that produces a liquid density of 1.00 kg/L for a given water concentration, depends on the value of W (table 8). TC0 Calculated difference in degrees Celsius between the temperature recorded on the strip chart and simultaneous calibration thermometer readings. Contents V TP Calculated distance in millimeters between the instrument reference point and the temperature pen trace at the time the data were recorded. TPC Measured distance in millimeters from the lower fixed pen trace to the temperature pen trace. UPT Average of the measurements in millimeters made at the beginning and end of each chart from the instrument reference point to the upper fixed pen, measured during service visits. W Ratio of water to total liquid in the precipitation gage collection tank. W0 Water concentration that produces a liquid density of 1.00 kg/L for a given temperature T0 (table 8). dps/dT Density/temperature gradient constant,-6.67X10"4 (kg/L)/ °C. dpJdW Antifreeze-water solution density variable, depends on the value of W (table 8). ps Antifreeze-water solution density. Ps/pw Relative density of antifreeze-water solution, where pw is the density of water.
