Sphere wall surface (%): 0.981768 Snow surface (%): 0.015751 Photodiode surface (%): 0.000145 ---------------- Calibration data Set of reflectance standards Serial number: IS3-RS-14-02N Released on: 2014-11-19 Last revised on: 2014-11-19 NOTE: this set was last revised more than 5 years ago. Please consider recalibrating it in the near future for optimal results. Standard # Signal (mV) Reflectance (%) #1 69.6 5.22 #2 112.6 10.44 #3 191.2 19.22 #4 507.4 48.3 #5 867.2 70.19 #6 1620.9 98.25 Number of standards used for calibration: 6 Overall calibration quality: Fair Overall residue for polynomial fit: 786.351 *** A fair quality calibration will strongly reduce the system accuracy. It is advised that you go through calibration again, or revise your standards. 2 standard(s) with excellent fitting: #4 #6 2 standard(s) with fair fitting: #3 #5 2 standard(s) with poor fitting: #1 #2 *** Information about the fit of individual standards is only indicative: because of the way polynomial regression works, the standard(s) responsible for a bad calibration quality might appear with a perfect fit, and vice-versa. Background (mV): 52.7 Optical parameters Fraction of collimated photons: 0.999 Reflectance of sphere wall: 0.9916 Electronics gain: 1,244 Comment on calibration: 2018-12-27 Snow Pit central 2 m ---------------- Acquisition data Sample number Series Sample signal Reflectance Specific surface area (SSA) Comment 1 200-912 cm 411.7 40.51 28.9 plain middle surface sample 2 200-912 cm 403.7 39.82 27.8 3 200-912 cm 429.1 41.99 31.4 4 192-187 cm 362.9 36.16 22.8 5 192-187 cm 372.6 37.05 24 6 192-187 cm 369.4 36.76 23.6 7 187-185 cm 310.8 31.19 17.5 8 187-185 cm 306.4 30.76 17.1 9 187-185 cm 307.9 30.91 17.2 10 185-182 cm 321.9 32.28 18.5 11 185-182 cm 326.7 32.75 19 12 185-182 cm 322.4 32.33 18.6 13 182-174 cm 282.4 28.33 15 14 182-174 cm 282.8 28.37 15.1 15 182-174 cm 282.2 28.31 15 16 174-168 cm 313.6 31.47 17.7 17 174-168 cm 306.9 30.81 17.1 18 174-168 cm 299.8 30.1 16.5 19 168-161 cm 269.7 27 14 20 168-161 cm 250.7 24.98 12.5 21 168-161 cm 261.8 26.17 13.4 22 161-150 cm 258.7 25.84 13.1 23 161-150 cm 260.8 26.06 13.3 24 161-150 cm 253.7 25.3 12.8 25 150-142 cm 253.2 25.25 12.7 26 150-142 cm 248.5 24.74 12.4 27 150-142 cm 251.9 25.11 12.6 28 142-132 cm 254.7 25.41 12.8 29 142-132 cm 241.9 24.02 11.9 30 142-132 cm 245.4 24.41 12.2 31 132-114 cm 253.9 25.33 12.8 32 132-114 cm 253.1 25.24 12.7 33 132-114 cm 248.5 24.74 12.4 34 114-102 cm 254.1 25.35 12.8 35 114-102 cm 255.4 25.49 12.9 36 114-102 cm 249.6 24.86 12.5 37 102-98 cm 234 23.15 11.3 38 102-98 cm 236.8 23.46 11.5 39 102-98 cm 230.6 22.78 11.1 40 98-85 cm 217.1 21.26 10.1 41 98-85 cm 218.2 21.38 10.2 42 98-85 cm 211.3 20.6 9.7 43 85-63 cm 217 21.25 10.1 44 85-63 cm 229 22.6 11 45 85-63 cm 225.4 22.2 10.7 46 63-53 cm 204.6 19.82 9.2 47 63-53 cm 204.2 19.78 9.2 48 63-53 cm 221.1 21.71 10.4 49 53-24 cm 218.8 21.45 10.2 50 53-24 cm 205.1 19.88 9.3 51 53-24 cm 186.9 17.75 8 very bottom of the layer 52 24-0 cm 204.1 19.77 9.2 53 24-0 cm 209.1 20.34 9.6 54 24-0 cm 198.9 19.16 8.8 55 0-1 cm 437.7 42.71 32.6 crusty surface sample 56 0-1 cm 457.7 44.35 35.7 crusty surface sample 57 0-1 cm 430.8 42.13 31.6 crusty surface sample 58 1-2 cm 416.9 40.95 29.6 59 1-2 cm 413.8 40.69 29.2 60 1-2 cm 398.9 39.4 27.2 61 2-3 cm 410.6 40.41 28.8 62 2-3 cm 413.8 40.69 29.2 63 2-3 cm 415.9 40.87 29.5 64 3-4 cm 391.6 38.75 26.3 65 3-4 cm 387.8 38.42 25.8 66 3-4 cm 393.6 38.93 26.5 67 4-5 cm 424.8 41.63 30.7 68 4-5 cm 413.8 40.69 29.2 69 4-5 cm 409.8 40.34 28.7
