1688 | 17 Aug | 1740 - 1741 1802 - 1814 1830 - 1836 1912 - 1953 |
North of Brasilia | Four small cerrado (grass and shrub) fires | See Hobbs' photos on Roll #1 photos #4-7 |
1690 | 21 Aug | 1802 - 1905 | Brazilia | Extensive measurements on 1 small prescribed cerrado burn. A few measurements, prior to prescribed burn, on another cerrado plume. | IBAMA prescribed burn. Also measurements from IBAMA Banderante (Riggan) and Lear jet (Brass) aircraft. Ground observations by Ottmar. (See Hobbs' photos on Roll #1 photos #12-17.) |
1692 | 24 Aug | 1723 - 1758 1826 - 1905 |
North of Cuiaba | Several grass and forest fires. Last plume studied was flaming combustion of trees. | Sampled last plume (from flaming combustion of trees) at several distances downwind. (See Hobbs' photos on Roll 2 photos #4-6.) Should be good for emission factors. Also good lidar, optical, and TDDR measurements. |
1693 | 25 Aug | 1750 - 2025 | West and north of Cuiaba | Slash burn of logged area in regular rows. | Many passes through plume. (See Hobbs' photos on Roll 2 photos #18-24 showing fuel rows and plumes.) Lots of humidigraphs. |
1695 | 28 Aug | 1717 - 1735 (Fire 1) 1802 - 1842 (Fire 2) 1902 - 1928 (Fire 1) |
West of Cuiaba | Sampled 2 plumes for emission factors. Smoldering grass fires, maybe some flames. (See Hobbs' photos Roll 4 photos #4-6.) | Sampled 2nd fire fairly extensively at several distances downwind. Good OEC data. Flight primarily devoted to two smoke-cloud interaction studies. |
1703 | 7 Sep | 1547 - 1814 | South-east of Porto Velho | Sampled 1 good plume for chemical measurements and another plume near by for physical measurements. Fire was slash burning of downed (dead) trees. | Flight devoted primarily to vertical profile over sunphotometers and CAR measurements. ER-2 overflight. |
1704 | 11 Sep | 1430 - 1522 1540 - 1541 1601 - 1609 |
South-east of Porto Velho | Sampled 2 plumes from slash burning of downed (dead) trees. (See Hobbs' Roll 5 photo #17.) | Good chemical measurements on 1st plume |
1705 | 12 Sep | 1714 - 2001 | South-east of Porto Velho | (1) Smoldering slash burn of dead trees some flames) produced white
and black smoke. (See Hobbs' Roll 5 photos #18-22.) (2) Some individual (smoldering) slash burns. (3) Flaming grass burn (black smoke). (See Hobbs' Roll 5 photo #23.) |
Flight largely devoted to individual plumes and smoke-cloud
interactions. Good optical measurements. (1) Emission factors, evolution, and measurements in and around cloud produced by fire. (3) Emission factors and physical measurements. |
1706 | 13 Sep | 1650 - 1723 | North-east of Porto Velho | Flaming slash burn on edge of forest. (See Hobbs' Roll 6 photos #1 and 2.) | Emission factors. Time evolution measurements, and effects on cloud. |
1706 | 13 Sep | 1814 - 1826 | North-east of Porto Velho | Pasture grass fire. (See Hobbs' Roll 6 photo #3.) | Emission factors, evolution, humidigraphs. |
1707 | 14 Sep | 1314 - 1315 | North-east of Porto Velho | Haze and cloud too thick to ground. | Transit flight. One bag for physical measurements on a plume at 9000ft. |
1708 | 14 Sep | 1810 - 1811 | East of Manaus | Slash burn | Transit flight. One plume sample. |
1710 | 16 Sep | 1400 - 1532 | ~100 miles south of Maraba | Smoldering combustion of primary forest and undergrowth. (See Hobbs' Roll 6 photo #4.) | Three samples of plumes for emission factors. (See Hobbs' Roll 6 photos #5-7 showing burned areas and ash, south of Maraba.) |
1711 | 16 Sep | 1845 - 1918 1930 - 2040 |
North-east of Maraba | (1) Pasture burning, some flames, brown. (2) Flaming combustion of trees and undergrowth. |
(1) Good chemical samples. (2) Extensive sampling of plume. (See Hobbs' Roll 6 photos #9-14 of clouds produced by fires in area sampled.) |
1712 | 17 Sep | 1622 - 1638 1634 - 1652 |
East of Maraba | (1) Flaming combustion of brush and palm trees. (2) Flaming grass fir (black smoke). |
(1) Emission factors. (2) Emission factors. Extinction cell measurements. Biggest fires sampled to date (very black). A3 activity and humidigraph growth. |
1713 | 17 Sep | 1852 - 2016 2036 - 2057 |
North-east of Maraba | Flaming combustion of pasture moving into brush and trees. | Emission factors. Good optical (OEC and A3) measurements. |
1716 | 20 Sep | 1742 - 1836 | North-west of Brazilia | Cerrado, with some flames. | Samples for emission factors at various distances downwind. (Good humidigraphs and OEC data.) Returned later to same fire and got further emission factor, etc. measurements. |
