Sulfates, Clouds and Radiation Brazil (SCAR-B) University of
Washington C131A (SCAR_B_UWC131A) Langley DAAC Data Set Document
Summary:
From 17 August to 20 September 1995, the University of
Washington's (UW) Cloud and Aerosol Research Group, with its Convair C-131A
research aircraft, participated in an intensive field study of smoke emissions
from various types of biomass burning over a large area of Brazil.
Twenty-nine research flights (~90 flight hours) in Brazil from 17 August -
20 September 1995.
Transcriptions of the in-flight voice recordings made on the C-131A.
Documentation of regional smoke properties from ~16° to 3° S and
from ~64° to 48° W. (~67 filter sets.)
One hundred and ten (110) photographs of fires, smoke, clouds and terrain.
Aerosol and gas (NO, NO2, SO2, CO, CO2, O3 and hydrocarbons) measurements
on smoke from ~16 cerrado and grass fires and ~16 forest and/or slash fires.
Twenty-three samples for "true" emission factors for particulate
(including CCN), NO, NO2, SO2, CO, CO2 and total volatile organic compounds
(VOCs).
Three thousand nine hundred and seventy measurements of aerosol size
distributions in regional haze and plumes.
One hundred and fifty-six cloud condensation nucleus (CCN) spectra for
smoke in individual plumes, in regional haze, and in cloud-processed smoke.
One hundred and thirty-seven measurements of volatility of aerosols (at
<=320°C).
Seventy measurements of humidification factor of aerosols from individual
fires and in regional haze.
Extensive black carbon measurements by four techniques (optical
extinction cell (OEC), aethelometer, Teflon filters, and thermal-optical). On
26 occasions, simultaneous measurements were obtained using all four techniques.
One hundred and thirty-five measurements of single-scattering albedo of
smoke from individual fires and in regional haze.
Twenty smoke-cloud interaction studies.
Seven direct aerosol "closure" experiments over NASA ground-based
sun photometers.
Six coordinated flights with NASA ER-2 (plus three other
"crossings").
Four flights during satellite overpasses (AVHRR and LANDSAT).
Seven dedicated surface reflectivity and smoke measurements with CAR.
The objectives of the research flights of the University of Washington's
(UW) Convair C-131A in the Smoke, Clouds And Radiation-Brazil (SCAR-B) field
study in Brazil, which took place between 17 August and 20 September 1995,
were to collect data needed to determine the following.
Emission factors of gases and particles from cerrado and tropical forest
fires in various stages of combustion.
The nature of the gases and particles in smoke plumes from various types
of biomass fires in Brazil.
The optical and radiative properties of smoke from biomass fires in Brazil.
Direct radiative forcing by smoke (through direct aerosol
"closure" measurements).
The effects of smoke on cloud microstructures, and the effects of cloud
scavenging on smoke.
The evolution of the physical and chemical properties of smoke (from local
to regional scales) from biomass burning in Brazil.
Comparisons of ground-based, airborne, and satellite-borne remote sensing
measurements of smoke from biomass fires in Brazil with in situ
measurements of the smoke.
The extensive measurements obtained aboard the UW Convair C-131A
aircraft in SCAR-B provided considerable data relevant to each of the topics
listed above.

The Langley DAAC performs an inspection process on this data
received by the data producer via ftp. The DAAC checks to see if the transfer
of the data completed and were delivered in their entirety. An inspection
software was developed by the DAAC to see if the code was able to read every
granule. The code also checks to see if every parameter of data falls within
the ranges which are included in the granule. This same code extracts the
metadata required for ingesting the data into the IMS. If any discrepancies are
found, the data producer is contacted. The discrepancies are corrected before
the data are archived at the DAAC.

The Langley DAAC provides multiple interfaces to access its data
holdings. The graphical and character user interfaces allow users to search
and order data; and web interfaces allow direct access to some data holdings
for immediate downloading or placing media orders, for searching the data
holdings, and downloading electronically available holdings, and for ordering
prepackaged CD-ROMs and videocassettes. All of these methods are easily
obtained from the Langley DAAC web site.
