---|---|---|---|---|---|---|
1692 | 24 Aug | 1723 - 1758 | ~100mi N of Cuiaba | See Hobbs' Roll #1 photos #19-24 and Roll #2 photos #1-3 for shots of smoke and Cu. | Cumulus | Measurements above, in, and below cloud. |
1695 | 28 Aug | 1717 - 1735 1902 - 1928 |
N of Cuiaba | Flaming combustion of grass and shrub | Cumulus | Two smoke-cloud interaction studies |
1701 | 6 Sep | 1450 - 1541 | NE of Porto Velho | Small fires (no large fires with flames) | Cumulus | Obtained measurements below cloud base, in-cloud, and near cloud top |
1702 | 6 Sep | 1845 - 2021 | NE of Porto Velho | Regional haze | Cumulus | Flight devoted to smoke-cloud interactions. Measurements below cloud base and in cloud. |
1703 | 7 Sep | 1547 - 1814 | SE of Porto Velho | Slash burning of downed trees | Cumulus, alto-cumulus, cumulus-fractus | In-cloud measurements at various levels and above and below clouds |
1704 | 11 Sep | 1430 - 1522 | SE of Porto Velho | Slash burn on edge of forest | Cumulus | Measurements in cloud and on smoke coming out of cloud. Good measurements on plume itself. A few measurements in other Cu at end of flight. |
1705 | 12 Sep | 1742 - 2001 | SE of Porto Velho | (1) Slash burn of dead trees (white smoke). (2) Black smoke from fresh grass fire. |
Cumulus | (1) Sampled smoke entering Cu, sampled Cu up to 13,000 ft and smoke in
outflow. (2) Sampled Cu cloud produced by fire. |
1706 | 13 Sep | 1650 - 1723 | NE of Porto Velho | Flaming slash burn at edge of forest. (See Hobbs' Roll 6 photos #1 and 2.) | Cumulus | Samples of smoke entering cloud, in cloud, and coming out of cloud.
Went through a few Cu later in flight (maybe warm rain event). |
1710 | 16 Sep | 1410 - 1532 | ~100mi S of Maraba | Smoldering combustion of primary forest and undergrowth. (See Hobbs' Roll 6 photo #4.) | Stratocumulus and cumulus | On first plume (for which emission factors were obtained) traced smoke to cloud base, cycles through cloud to cloud top, back down again. CCN sample below cloud base (in smoke?). Sampled more clouds on return to Maraba. |
1711 | 16 Sep | 1845 - 1918 1930 - 2040 |
NE of Maraba | (1) Pasture burning, some flames. (2) Flaming combustion of trees and undergrowth. | Cumulus humilis and cumulus congestus | (1) Good chemical and physical measurements of smoke plume followed by
cloud samples. (2) Extensive sampling of smoke below cloud base. Found smoke exiting cloud on 2nd try (lidar profile of plume). Probably best data set on smoke-cloud interactions to date. (See Hobbs' Roll 6, photos #9-14 for smoke and cumulus clouds.) Good optical, humidigraph, and A3 measurements in smoke. |
1712 | 17 Sept | 1404 - 1604 1622 - 1638 1639 - 1652 |
E of Maraba | (1) Regional smoke (2) Flaming combustion of brush and palm trees (3) Flaming combustion of grass fire |
Cumulus | (1) Filters, etc. above cloud top, at cloud level, and between and
below clouds, in regional smoke collected cloud water sample).
Later in flight got sample of smoke exiting cloud. (2) Good samples in cloud and below cloud base. (3) Following measurements in smoke plume, got measurements ~1000ft above cloud base. (SO2 removed by cloud.) |
1713 | 17 Sep | 1852 - 2016 2036 - 2057 |
East of Maraba | Flaming combustion of pasture (?) moving into brush | Cumulus complex | Emission factors of smoke followed by sampling of cloud and air detrained by cloud at various levels. Humidigraph samples in and out of cloud. Signal on A3 for cloud samples. Smoke sampled aloft was not there in morning flight; therefore, it was probably "pumped" there by Cu during the day. |
1714 | 18 Sep | 1201 - 1340 | Transit from Maraba to Porto Nactional | Regional smoke (pumped up by clouds on Sep 17?) | Cumulus | Some cloud measurements plus filters, CCN, DMPS and humidigraphs. |
1716 | 20 Sep | 1742 - 1836 1909 - 1918 |
NW of Brasilia | Cerrado, with some flames | Cumulus | Sampled smoke below cloud, just above cloud base, and near middle of cloud. Further measurements in a new cloud produced by same fire. Later sampled Cu not directly affected by any one plume but by ambient smoke. |
