description: Time-series of satellite-derived vegetation proxies and tree-rings widths (TRW) are similar, providing temporal records of forest productivity change from different perspectives and processes. Previous research on this relationship has focused on temperature or moisture limited coniferous forests, using lower spatial resolution (e.g., 8000 m) satellites and normalized difference vegetation index (NDVI) to test relationships over 15-30 years. There is an opportunity to leverage recent advances in building Landsat (30 m) time-series to expand comparisons into new forest types (e.g., coniferous vs. deciduous), areas (e.g., fragmented forests) and over longer periods (e.g., nearly 50 years). However, a better understanding of factors that influence relationship strength is required. We compared tree-ring measurements, converted to a ring width index (RWI), and Landsat tasseled cap angle (TCA) derived canopy cover (CC) from 1972 to 2018 across 16 deciduous, mixed, and coniferous stands in southern Ontario, Canada. For all chronologies, overall relationship strength was assessed with correlation approaches (RWI-CC, both vs. climate), and shorter-term increase-decline trends were compared with segmented regression. There were significant forest type differences, with coniferous chronologies correlating stronger with CC than deciduous. Deciduous chronologies and CC had opposite connections with summer temperature, with climate warming increasing CC and coniferous RWI but not deciduous RWI from 1980 to 2010. More recent decline at most sites appears related to a major ice storm, but multiple factors may be coexisting. We tested the utility of tree-rings for validating nearly 50 years of Landsat-observed change in urban-rural temperate forests, identifying useful connections at coniferous sites. However, there are limitations to comparing long-term Landsat time-series (based on yearly summer data) with annual tree-ring growth.

title: NOAA/WDS Paleoclimatology - Filion - Lac Ritchie - LALA - ITRDB CAN713

description: Tree ring data from the International Tree Ring Data Bank and World Data Center for Paleoclimatology archives.  Most data sets include raw treering measurements (most are annual ring width, with some collections of earlywood or latewood width or wood density), plus chronologies (standardized growth indices for a site compiled from multiple treering samples). Reconstructions of climate variables are included with some of these data sets.  Each data type is stored in a separate data file; the data type is coded into the file name.
