Book Description
A liquid-helium-cooled long-wavelength infrared spectrometer was successfully launched on 22 March 1973 from the Poker Flats Research Facility, Alaska. This spectrometer, which employed a circular variable filter (CVF), was developed over a period of five years and provided the first measurements of the infrared spectrum of the upper atmospheric emissions between 7 and 24 micrometers. The data processing proceeded in a step-by-step manner to provide accurate final data with error limits and an understanding of the spectrometer performance. Each step of the data processing is presented in this report which will provide engineers with information on the spectrometer performance and data analysts with the basis for the final assignment of error limits. Similar procedures can also be used for the data reduction of other CVF flights.

LWIR (7-24 Micrometer) Measurements from the Launch of a Rocketborne Spectrometer Into an Aurora (1973)
Author: James W. Rogers
Publisher:
ISBN:
Category : Auroras
Languages : en
Pages : 132
Book Description
A liquid-helium-cooled, long-wavelength infrared (LWIR) spectrometer was successfully launched by the Air Force Geophysics Laboratory onboard a Black Brant VC rocket (A18.006-2) on 22 Mar 1973 from the University of Alaska's Poker Flat Research Range at Chatanika, Alaska. This flight was part of the Defense Nuclear Agency ICECAP 73 Program. The spectrometer, which employs a circular-variable filter (CVF), was developed by AFGL and Utah State University and has provided the first measurements of the altitude profile of the infrared spectrum of the upper-atmospheric emissions between 7 and 24 micrometers. During an IBC II aurora, data were obtained on the 15-micrometer carbon dioxide emission from 65 to 150 km and on the 9.6 micrometer ozone emission between 45 and 100 km. In addition, emission data on the long-wavelength wing of the 6.3 micrometer water band between 6.7 and 7.6 micrometers were also obtained between 50 and 75 km. Above 100 km, significant unidentified emission was observed at 9.3 micrometers with weaker features at 6.9, 7.3, 8.0, 11.1, and 12.3 micrometers. This report documents in detail the data obtained along with the rocket and payload performance, the auroral conditions at launch and a comparison with theoretical models.

LWIR (7-24 Micrometer) Measurements from the Launch of a Rocketborne Spectrometer Into a Quiet Atmosphere (1974)

ISBN:
Category : Atmosphere, Upper
Languages : en
Pages : 124
Book Description
A liquid-helium-cooled, long-wavelength infrared (LWIR) spectrometer was successfully launched on 14 Feb 1974 from the University of Poker Flat Research Range at Chatanika, Alaska, part of the DNA ICECAP 74 Program. The Spectrometer, which employs a circular-variable filter, was almost identical to one flown on 22 Mar 1973 that provided the first measurements of the altitude profile of the infrared spectrum of the upper-atmospheric emissions between 7 and 24 micrometers. The 1973 measurements were from an energetically pumped atmosphere during the occurrence of an IBC II aurora. The objective of the 1974 flight was to obtain emission data from an aurorally quiet atmosphere to determine the contribution of the auroral energy input to the data obtained in 1973. The payload was successfully launched during nonauroral conditions, and data were obtained on the 15 micrometer carbon dioxide (nu 2) emission from 74 to 160 km and on the 9.6 micrometer ozone (nu 3) emission between 74 and 110 km. Above 110 km, significant unidentified emission was again observed at 9.3 micrometers.
