Decoupling between Plant Productivity and Growing Season Length under a Warming Climate in Canada’s Arctic

Autor: Ian Olthof, Yu Zhang, Paul Zorn, Wenjun Chen, Lori White, Sylvain G. Leblanc, Robert H. Fraser

Publikováno v: American Journal of Climate Change. :334-359

Given the short duration of growing season in the Arctic, a strong correlation between plant productivity and growing season length (GSL) is conventionally assumed. Will this assumption hold true under a warming climate? In this study, we addressed t

Revitalizing Complex Analysis

Autor: Russell W. Howell, Alan Noell, Paul Zorn

Publikováno v: PRIMUS. 27:755-757

Complex analysis, despite its beauty and power, seems to have has lost some of the prominence it once enjoyed in undergraduate mathematics, science, and engineering. Conversations with colleagues a...

A biophysically based and objective satellite seasonality observation method for applications over the Arctic

Autor: Ian Olthof, Rasim Latifovic, Norah Foy, Jean Poitevin, Donald McLennan, Wenjun Chen, Paul Zorn, Yu Zhang, Robert H. Fraser

Publikováno v: International Journal of Remote Sensing. 35:6742-6763

Despite wide applications of remote-sensing data with high temporal resolution for monitoring phenology, two persistent problems have prevented the realization of their full potential. The first is the subjectivity in defining thresholds for a phenol

Evaluating and reducing errors in seasonal profiles of AVHRR vegetation indices over a Canadian northern national park using a cloudiness index

Autor: Jean Poitevin, Ying Zhang, Paul Zorn, Rasim Latifovic, N. Foy, Junhua Li, Z. Chen, J. Quirouette, Ian Olthof, Donald McLennan, Robert H. Fraser, H. M. Stewart, Wenjun Chen

Publikováno v: International Journal of Remote Sensing. 34:4320-4343

High-temporal coarse resolution remote-sensing data have been widely used for monitoring plant phenology and productivity. Residual errors in pre-processed composite data from these sensors can still be substantial due to cloud contamination and aero

Propagation of errors associated with scaling foliage biomass from field measurements to remote sensing data over a northern Canadian national park

Autor: Jean Poitevin, R. Sharma, Donald McLennan, H. M. Stewart, Robert H. Fraser, Zhaohua Chen, Ian Olthof, Paul Zorn, Junhua Li, J. Quirouette, Wenjun Chen, Ying Zhang, Rasim Latifovic

Publikováno v: Remote Sensing of Environment. 130:205-218

If a change detection result based on time series of remote sensing data indicates that there was a 10% increase in an ecosystem property between two years over a specific land area, does it mean there was a real change in the ecosystem property, or
