ABLE 2-A/B ABLE 3-A/B Data Archive CD-ROM (April, 2002)

This CD-ROM contains data from the National Aeronautics and Space Administration (NASA) Global Tropospheric Experiment (GTE) Amazon Boundary Layer Experiment (ABLE 2) and the Arctic Boundary Layer Experiment (ABLE 3). One section of the CD-ROM describes and contains data from phase A of ABLE 2 (ABLE 2A) conducted in July-August 1985, and phase B (ABLE 2B), conducted in April-May 1997. Both phases of ABLE 2 were conducted jointly with the Instituto de Pesquisas Espaciais (INPE), the Brazilian Space Agency. The ABLE 2A mission involved the NASA Electra aircraft, with flights originating from Manaus, Brazil and an instrumented ground site in the Ducke Forest Reserve near Manaus. The ABLE 2B mission also involved the NASA Electra aircraft with flights from Manaus, but with a more extensive ground program involving tethered balloon measurements at three ground sites (Embrapa, Carapana, and Ducke), and rawinsonde launches from sites surrounding the Amazon basin. The three tethered balloon ground sites formed a "meso-scale triangle" approximately 50 km on each side. Aircraft measurements were coordinated with the tethered balloon measurements conducted at each of these ground sites. 

The next section of the CD-ROM describes and contains data from phase A of ABLE 3 (ABLE 3A) conducted in July-August 1988, and phase B (ABLE 3B), conducted in July-August 1990. ABLE 3A involved the NASA Electra aircraft, with flights originating from Point Barrow and Bethel, Alaska, and an instrumented ground site near Bethel, Alaska. The ABLE 3B mission, conducted
jointly with the Canadian Northern Wetlands Study (NOWES), also involved the NASA Electra aircraft with flights originating from North Bay, Ontario and Goose Bay, Labrador, and an instrumented ground site near Schefferville, Quebec. The data on this CD-ROM consist of in situ and remotely sensed measurements collected onboard the Electra aircraft; calculations of air parcel back trajectories associated with air mass encountered along the Electra flight paths; in situ measurements from the ground stations; and data files containing in situ measurements aboard the Electra aircraft merged to several common time bases.

The data in the ABLE 2 section on this CD-ROM consist of in situ and remotely sensed measurements collected onboard the Electra aircraft; in situ measurements from the ground stations; the Amazon basin scale rawinsonde measurements; and data files containing in situ measurements aboard the Electra aircraft merged to several common time bases.

The data in the ABLE 3 section on this CD-ROM consist of in situ and remotely sensed measurements collected onboard the Electra aircraft; calculations of air parcel back trajectories associated with air mass encountered along the Electra flight paths; in situ measurements from the ground stations; and data files containing in situ measurements aboard the Electra aircraft merged to several common time bases.
