THE LAUNCH HAS TIME BUFFER OF PLUS 30 MINUTES TO ACCOMMODATE ANY FAILURES THAT MIGHT CAUSE A DELAY. THE TOTAL PAYLOAD OF THE BALLOON IS ABOUT 410 GRAMS, BEING CLASSIFIED AS LIGHT IN ACCORDANCE WITH ICAO ANNEX2, APPENDIX 5, NUMBER 1. THE BALLOONS ARE EXPECTED TO CLIMB AT 5 TO 6 METERS PER SECOND AND REACH UP TO 25 KILOMETERS HIGH WITHIN 120 MINUTES. AFTER FLIGHT TERMINATION THE DESCENT RATE IS ESTIMATED TO BE ABOUT 10 METERS PER SECOND. THE TRAJECTORY OF EACH BALLOON WILL DEPEND ON THE METEOROLOGICAL AND ATMOSPHERIC CONDITIONS AT LAUNCH TIME AND THE TERMINATION OF THE FLIGHT MAY OCCUR AT A SIGNIFICANT DISTANCE FROM THE LAUNCHING POSITION.SFC25000M AMSLOTHER:ICAO<pre> A4585/26 NOTAMN Q) LPPO/QWLLW/IV/NBO/W /000/821/3905N02802W030 A) LPPO B) 2608130327 C) 2608301800 D) 13 0327-0657 1138-1508, 14 1430-1800, 18 0333-0703, 23 1131-1501, 24 1442-1812, 27 1148-1518, 28 0346-0716 1127-1457, 30 1430-1800 E) AS PART OF THE EASTERN NORTH ATLANTIC INTERNATIONAL PROJECT, ATMOSPHERIC RESEARCH UNMANNED BALLOON FLIGHTS WILL BE LAUNCHED FROM THE GRACIOSA ISLAND ARM (ATMOSPHERIC RADIATION MEASUREMENT) FACILITY, LOCATED AT POSITION 390528N 0280134W.
