Pressure (mb) Temperature (air) (K) Sun Sensor Theta (K) 0 17 Air Temperature Data from the Balloon Ozone Instrument flown aboard the MkIV gondola from Esrange, Sweden 67.9 N, 21.1 E. MkIV flight 20030401. Pressure and Temperature retrieved from on-board data. The sun and warm air from the gondola cause high readings (by up to 20K) in the 1-sec T data. To attempt to retrieve an appropriate ambient profile, the 1-sec data were averaged over 5 sec, and then for each 100 sec interval (20 5-sec averages) the lowest T was found, along with the corresponding P (also 5-sec avg) and UT time. These are listed below. The derived "minimum-T" data follow the lower edge of the 1-sec data, with a small number of points still contaminated. These obviously bad points have been deleted, but some high points may still remain. The 4th column is the Sun Sensor reading, which is 0 in the dark, 10 full scale (full overhead sun). The sensor is uplooking, so readings for the low sun angles from Kiruna are fairly low. Ascent was at night so should not be affected by sun. Descent was sunlit. The full 1-sec temperature data are available on request. Theta is calculated from theta=T*(1000/p)**0.286 UTsec P(mb) Tair Sun Theta 85654 874.79 261.3 0.0 271.5 85759 811.98 257.7 0.0 273.5 85859 756.45 255.9 0.0 277.1 85959 705.68 253.9 0.0 280.5 86059 657.04 250.6 0.0 282.6 86149 620.78 249.3 0.0 285.7 86254 580.77 247.8 0.0 289.4 86359 542.06 244.7 0.0 291.5 86454 506.87 241.4 0.0 293.2 86559 466.88 237.3 0.0 295.1 86659 431.53 233.5 0.0 296.9 86759 398.66 229.2 0.0 298.1 86859 368.17 224.4 0.0 298.7 86959 339.62 221.2 0.0 301.3 87059 315.74 219.9 0.0 305.8 87159 289.56 215.8 0.0 307.6 87259 264.43 211.2 0.0 308.9 87294 256.67 209.4 0.0 308.9 87364 245.18 212.4 0.0 317.5 87479 232.62 214.8 0.0 325.9 87564 226.95 215.8 0.0 329.8 87674 216.50 218.1 0.0 337.8 87774 206.71 219.4 0.0 344.5 87894 196.59 220.7 0.0 351.4 87964 190.81 221.7 0.0 356.0 88079 181.01 222.0 0.0 361.9 88219 169.91 222.6 0.0 369.6 88269 165.84 222.7 0.0 372.3 88364 158.03 223.1 0.0 378.1 88554 143.12 222.4 0.0 387.8 88659 134.08 221.9 0.0 394.2 88664 133.79 221.9 0.0 394.4 88764 126.98 222.8 0.0 402.0 88884 119.65 223.3 0.0 409.9 89059 108.16 222.3 0.0 419.9 89079 106.94 221.8 0.0 420.4 89224 99.10 222.1 0.0 430.3 89314 94.63 222.5 0.0 436.7 89459 86.91 222.3 0.0 447.0 89554 82.53 221.9 0.0 453.0 89654 77.83 221.4 0.0 459.5 89749 73.51 221.2 0.0 466.7 89819 70.60 220.8 0.0 471.3 89954 65.35 220.6 0.0 481.4 90059 61.78 220.5 0.0 488.8 90159 58.04 219.7 0.0 495.9 90189 57.04 219.0 0.0 496.8 90304 53.54 219.5 0.0 507.1 90394 51.07 219.2 0.0 513.2 90464 49.30 219.8 0.0 519.8 90564 47.42 220.7 0.0 527.8 90734 43.91 220.5 0.0 539.1 90834 42.07 220.4 0.0 545.4 90899 40.85 220.1 0.0 549.4 91059 37.85 219.9 0.0 560.9 91159 35.67 219.3 0.0 568.9 91244 33.89 218.4 0.0 574.9 91284 33.19 218.4 0.0 578.4 91444 31.28 219.3 0.0 590.7 91494 30.54 218.7 0.0 593.2 91649 28.94 219.9 0.0 605.8 91759 27.37 219.4 0.0 614.1 91784 27.06 218.7 0.0 614.0 91884 26.41 218.7 0.0 618.4 91974 26.02 219.0 0.0 621.7 92124 24.12 219.4 0.0 636.5 92254 22.00 217.7 0.0 648.7 92324 20.91 216.9 0.0 655.6 92404 19.98 215.9 0.0 661.2 92524 18.81 215.8 0.0 672.5 92639 18.15 216.3 0.0 680.7 92674 17.96 215.5 0.0 680.3 92819 16.91 216.1 0.0 694.2 92944 16.18 216.3 0.0 703.5 92964 16.13 216.8 0.0 705.9 93144 15.18 217.1 0.0 719.2 93184 14.91 217.3 0.0 723.6 93319 14.45 217.5 0.0 730.8 93439 13.48 216.2 0.0 740.8 93504 13.02 216.7 0.0 750.1 93564 12.85 216.5 0.0 752.0 93724 12.26 216.9 0.0 763.7 93859 11.51 216.1 0.0 774.6 93899 11.37 215.2 0.0 774.5 94054 10.61 212.8 0.0 780.9 94134 10.34 215.3 0.0 796.0 94254 9.81 214.5 0.0 805.2 94304 9.60 213.2 0.0 805.0 94449 9.67 214.8 0.0 809.6 94479 9.55 217.3 0.0 822.1 94649 9.21 219.8 0.0 840.0 94679 9.09 220.2 0.0 844.4 94784 8.69 222.1 0.0 863.1 94959 7.94 219.8 0.0 876.1 94984 7.79 218.0 0.0 873.8 95149 7.20 211.2 0.0 865.8 95164 7.17 210.6 0.0 864.5 95359 7.29 217.3 0.0 888.1 95444 7.13 215.5 0.0 886.1 95464 7.18 216.1 0.0 886.9 95574 7.39 218.0 0.0 887.2 95674 7.17 217.9 0.0 894.5 95794 7.28 217.7 0.0 889.6 95929 7.19 216.3 0.0 887.3 95979 7.11 214.6 0.0 883.0 96159 7.15 217.9 0.0 895.4 96219 7.00 214.8 0.0 887.9 96264 7.06 216.1 0.0 891.1 96449 7.12 217.2 0.0 893.2 96489 7.05 211.3 0.0 871.6 96574 7.18 216.0 0.0 886.6 96739 7.04 213.1 0.0 879.3 96764 7.01 214.2 0.0 884.9 96954 7.11 216.6 0.0 891.0 96994 7.05 213.1 0.0 879.0 97064 7.18 217.2 0.0 891.0 97254 7.09 218.7 0.0 900.7 97334 7.12 218.2 0.0 897.3 97424 7.28 216.0 0.0 882.9 97514 7.22 218.7 0.0 896.2 97599 7.13 220.7 0.0 907.6 97664 7.21 222.6 0.0 912.1 97839 7.29 222.0 0.0 907.1 97954 7.29 222.2 0.0 908.0 97969 7.31 222.4 0.0 907.8 98154 7.18 223.8 0.0 918.4 98239 7.20 223.2 0.0 915.0 98354 7.25 221.0 0.0 904.3 98434 7.07 222.2 0.0 915.7 98549 7.29 220.8 0.0 902.0 98564 7.34 221.0 0.0 901.0 98714 7.26 223.5 0.0 914.1 98859 7.29 221.8 0.0 906.4 98934 7.21 219.3 0.0 898.7 98989 7.24 221.2 0.0 905.6 99084 7.42 222.3 0.0 903.8 99194 7.39 221.8 0.0 902.5 99264 7.20 223.9 0.0 918.2 99449 7.29 223.6 0.0 913.5 99494 7.23 220.0 0.0 900.9 99639 7.12 223.0 0.0 917.3 99744 7.07 222.7 0.0 918.0 99859 7.12 223.9 0.0 920.8 99954 7.13 219.3 0.0 901.4 99969 7.13 221.3 0.0 909.7 100099 7.18 223.7 0.0 918.0 100209 7.23 219.8 0.0 900.3 100359 7.11 222.1 0.0 913.9 100449 7.11 218.3 0.0 898.2 100529 7.19 219.1 0.0 898.8 100569 7.21 224.0 0.0 918.1 100744 7.09 223.0 0.0 918.6 100809 7.10 222.2 0.0 914.7 100934 7.16 219.6 0.0 902.0 101039 7.16 219.7 0.0 902.0 101134 7.07 223.8 0.0 922.6 101199 7.00 221.5 0.0 915.4 101339 7.04 221.0 0.0 912.2 101389 6.97 218.0 0.0 902.5 101499 6.86 223.2 0.0 928.1 101564 6.87 224.2 0.0 931.9 101759 11.16 220.9 0.0 799.0 101784 13.84 219.7 0.0 747.3 101914 31.79 220.2 0.0 590.5 102009 49.45 219.9 0.0 519.6
