| Through the use of remote sensing technology, researchers are able to monitor inaccessible regions common to the Canadian Arctic. Parks Canada currently receives GEOCOMP-n 10-day composite AVHRR imagery from the Manitoba Remote Sensing Centre. The federal agency is using the data to develop methods for monitoring various ecosystem variables within protected areas located throughout northern Canada. This study, located in Tuktut Nogait National Park (TNNP), Northwest Territories, uses GEOCOMP-n imagery to monitor the timing of four key growing season events during the 1999 to 2001 period. The specific objectives of the study were: (1) To determine which vegetation index is best suited for use with AVHRR data in the TNNP study area, (2) To describe the characteristics of basic components of the GEOCOMP-n data set for TNNP, and (3) To produce unbiased estimates of key timing events in the Arctic growing season using GEOCOMP-n data.;Using both quantitative and qualitative criteria, field data were analyzed to assess four vegetation indices.
