ANCILLARY INFORMATION

Flight: 99-006-04
Date: September 14, 1999
Aircraft: DOE B-200 Kingair
Deployment: B200 Autumn 1999
Flight Location: Medicine Lake Volcano, CA
Principal Investigator: Christensen (ASU)
Additional Sensors: RC-30 (CIR)
Objective: This data set will be used in conjunction wih a recently awarded MTPE grant by NASA to study the effects of monitoring explosive eruptions with TIR. The information gained from MASTER on these inactive domes will be applied to future ASTER monitoring of active volcanoes. Several different remote sensing techniques will be used to evaluate these variables. (1) Linear deconvolution of thermal infrared (TIR) spectroscopic data will be used to assess lava vesicularity, which can be related to volcanic content. (2) For lavas of a given vesicularity, similar analysis can reveal chemical composition, which correlates with lava eruption temperature and rheology. (3) SAR can be used to calculate surface block sizes, which reflect the thickness of the dome's cooled carapace. (4) DEMs will be used to measure sub-flow topography and changes in flow volume.

Data Evaluation
In many flights during the 99-006 deployment, a minor pixel offset occured in channels 20-22. In addition, some flights (for example 99-006-08 and 99-006-14) contain banding in channel 22. This banding was a result of the analog offset in channel 22 being fixed at a value of 1024, meaning the digital to analog converter did not move through the entire signal range.
