AAOE April 26, 1989
This CDROM contains data pertaining to the Airborne Antarctic Ozone
Experiment (AAOE) which was based in Punta Arenas, Chile during August
and September 1987. The data is primarily that collected onboard the
NASA ER-2 and DC-8 aircraft, along with ozonesonde data collected at
four Antarctic stations--Halley Bay, McMurdo, Palmer Station, and the
All files within this release are standard ASCII files
with variable length records. The file naming convention uses a two
character prefix to identify the instrument followed by a six digit
number giving the year, month, and day (GMT) of the flight (or balloon
launch). A three character extension of ER2, DC8, or OZn is used to
denote the data is from the ER-2, DC-8, or ozonesonde (OZ1 for the first
launch, OZ2 for the second launch on a particular day).
- The DOCUMENT directory contains several files documenting
the contents of this release.
- CATALOG.DOC contains a list of the principal investigators,
their instruments, measurements, and their addresses. Tables showing
the available aircraft data and appropriate file name prefix's
are also given.
- HALLEY.DOC contains additional information about the
ozonesondes launched at Halley Bay, Antarctica.
- FORMAT.DOC gives the format specifications which all
experimenters were encouraged to use when writing time series
data files for data exchange. The standard format includes header
information which describes the data, and the data in the form
of time series. Some of the measurements (ie. balloon and lidar
soundings, and those with nonuniform sampling intervals) are not
easily cast as time series with constant sampling intervals so
some of the data files have unique formats. But most of the ER-2
data files and some of the DC-8 files follow this standard format
(with the exception that we have changed the file name extensions
from A1 to ER2 or DC8). At least, this document may serve as a
guide for reading the data files.
- SOFTWARE.DOC contains documentation on Fortran subroutines
included in the SOFTWARE directory which can be used to read those
files which are in the standard format described in FORMAT.DOC.
- 2.2 The SOFTWARE directory contains several Fortran subroutines
which can be used to read those data files which are in the standard
format described in FORMAT.DOC.
- 2.3 The DATA directory has three subdirectories for the ER-2, DC-8,
and ozonesonde data files. In general, each file contains data for
only one flight so the aircraft data is organized by flight date.
However, files for the ER-2 Multi Filter Sampler and the DC-8 Fourier
Transform Spectrometer and Mark IV Interferometer contain data for
all flights in a single file. These exceptions have been placed in
MISC subdirectories. The ozonesonde data has been organized by launch
