Lake surface temperature (LST) is an important attribute that highlights regional weather and climate variability  \n10 and trends. The spatial resolution and thermal sensors on Landsat platforms provide the capability of monitoring the temporal and spatial distribution of lake surface temperature on small to medium size lakes. In this study, a retrieval algorithm was applied to the thermal bands of Landsat archives to generate an LST dataset (North Slave LST dataset) for 535 lakes in the North Slave Region (NSR) of the Northwest Territories (NWT), Canada, for the period of 1984 to 2021. North Slave LST was retrieved from Landsat-5 TM, Landsat-7 ETM+ and Landsat-8 OLI/TIRS; however, most of the dataset was created from the  \n15 thermal bands of Landsat-5 (43%) due to its longevity (1984-2013) . Cloud masks were applied to Landsat images to eliminate cloud cover. In addition, a 100-meter inward buffer was applied to lakes to prevent pixel mixing with shorelines. To evaluate the algorithm applied, retrieved LST was compared with in-situ data and Moderate Resolution Imaging Spectroradiometer (MODIS) LST observations. A good agreement was observed between in-situ observations and North Slave LST with a mean bias of 0.12 °C and an RMSD of 1.7 °C. The North Slave LST dataset contains more available data for warmer months (May  \n20 to September) (57.3 %) compared to colder months (October to April) . The average number of images per year for each lake across the NSR ranged from 20 to 45. The North Slave LST dataset available at [https://doi.org/10.5683/SP3/J4GMC2](https://doi.org/10.5683/SP3/J4GMC2) will provide communities, scientists, and stakeholders with spatial and temporal changing temperature trends on lakes for the past  \n38 years.  \n25 1 Introduction  \nLake surface temperature (LST) is a significant indicator of climate change and is crucial to lake ecosystems (Livingstone et al., 2005; G. Zhang et al., 2019) . Several ecological, biological, and hydrogeochemical processes are influenced by temperature in lakes (Schneider & Hook, 2010) . Lake warming can result in a decrease in ice cover, changes in over-lake wind speeds, and  \nchanges in water column stratification (Austin & Colman, 2007; Desai et al., 2009; Kraemer et al., 2015; Magnuson et al., 30 2000) . Land-water-atmosphere system ’s energy and material exchange processes can also be reflected in lake surface  \ntemperature (Huang et al., 2017; Yang et al., 2020) and hence recognised as an essential climate variable. As a significant  \nvariable in regional studies, the impact and relationship of LST to weather, climate and lake processes have been explored by other studies, including influences on the weather (Eerola et al., 2014; Kheyrollah Pour et al., 2017; Kheyrollah Pour, Duguay, et al., 2014; Kheyrollah Pour, Rontu, et al., 2014) , climate (Moigne et al., 2016; Wang et al., 2021), precipitation (X. Zhang et  \n35 al., 2016), lake effect snow (Shi & Xie, 2019) and lake overturning (Fichot et al., 2019) . Observations of lakes worldwide have reported increased lake temperatures associated with global warming resulting in changes to the underlying lake system (O’Reilly et al., 2015; Woolway et al., 2019) . Long-term records of lake surface temperature are therefore necessary to understand the thermal mechanism underlying lake processes, inclu","cbCaikqZQ0Cfgmy5","https://ap.wps.com/l/cbCaikqZQ0Cfgmy5","pdf",2833495,37,"English","# Abstract\n# 1 Introduction","[{\"question\":\"What does the study produce for the North Slave Region?\",\"answer\":\"It produces an LST dataset for 535 lakes in the North Slave Region for the period 1984 to 2021.\"},{\"question\":\"Which Landsat sensors and years are used in the dataset?\",\"answer\":\"The dataset uses Landsat-5 TM, Landsat-7 ETM+, and Landsat-8 OLI/TIRS, spanning 1984 to 2021, with much data derived from Landsat-5 due to its longevity.\"},{\"question\":\"How was the retrieval approach validated?\",\"answer\":\"Retrieved LST was compared with in-situ measurements and MODIS LST observations, showing a mean bias of 0.12 °C and an RMSD of 1.7 °C.\"}]","Lake Surface Temperature Dataset in the North Slave Region - Manuscript | PDF",1790499053,93]
