| Summary: | A fiber-optic DTS (distributed temperature sensing) system using Raman-scattering optical time domain reflectometry was implemented at a research site in the interior of Alaska (Poker Flat Research Range) to delineate the spatiotemporal characteristics of the variations in air, surface, and ground temperatures associated with the boreal forest heterogeneity in terms of surface and canopy conditions. This is the last portion of the Loop1 measurements, which started in 2012, continued with occasional partial and total interruptions due to several factors, and terminated because of the malfunction of the DTS equipment. In the Loop1 measurement, a fiber-optic cable sensor (multi-mode, GI50/125, dual-core; 3.4 mm) was deployed across the landscape to measure temperatures at high spatiotemporal resolution (0.5 m intervals, every 30 minutes) horizontally across the different land surface cover types (i.e., relict thermokarst lake, open moss, shrub, deciduous forest, sparse spruce, and dense spruce). It also had ... |
