(2018) <p> The dataset includes two csv files, two xlsx files and one readme txt file with more detailed metadata:</p> <p> Microclimate_loggerdata_all.csv: All logger temperature and humidity measurements including the double measurements on each site from 2 loggers.</p> <p> Microclimate_loggerdata_minmax.csv: Daily minimum, maximum and mean temperature, minimum and maximum humidity values per site.</p> <p> Microclimate_field_protocols.xlsx: Fieldwork protocols including comments if a logger was overgrown or damaged and with site data on soil moisture and forest type etc.</p> <p> Microclimate_response_predictor_values.xlsx: Clean table with all response values (monthly Tmin and Tmax) and predictors (on-site measured and remotely sensed) that were used for the microclimate models.</p> <p> README.txt: Detailed metadata for each column in each table in the data files. <p>203 microclimate loggers (iButtons) were installed near-ground across the central Swedish forest in an area of ~16 000 km² (including parts of the counties of Värmland, Örebro, Västmanland and Dalarna). The loggers were placed ca 5 cm above ground in an inverted plastic cup that was taped onto a wooden stick in order to protect them from rain and direct sunlight. Loggers were brought out in May 2015, read out in September 2015, April 2016 and September 2016.</p> <p> All loggers measured temperature and half of them also air humidity three times a day (ca. at 00:00, 3:00, 6:00, and so on) from June 2015 to August 2016. At some places and during some periods there were two temperature-only loggers in one cup measuring simultaneausly. The temperature measurements of the two loggers in the same pair were sometimes very different (up to several degrees). When extracting daily minimum and maximum temperatures for each site, we picked the less extreme value from the two loggers. For the daily mean temperature we averaged over both loggers.</p> <p> Alternative contact person for this dataset: <a href="">Kristoffer Hylander</a>, Department of Ecology, Environment and Plant Sciences, Stockholm University.</p> <p> The <a href="">high resolution temperature maps</a> derived from these measurements are available as a separate dataset.
