Extreme Temperature and Dew Point Events in North America
Description
This dataset is the compilation of four different seasonally-relative extreme events for North America: extreme warm events (XWEs), extreme cold events (XCEs), extreme humid events (XHEs), and extreme dry events (XDEs). Each of these extreme events are calculated on a daily basis from 1979-2016 for 18,661 locations in North America. All extremes are relative to the time of year - essentially a seasonal curve of the 95th and 5th percentiles of the data at each location were created, and days that had 2-meter temperatures (or 2-meter dew points) that were >95th percentile were deemed XWEs (or XHEs for dew points), and days that were <5th percentile were considered XCEs (or XDEs for dew points). The article detailing the development of this dataset is: Lee, CC, Obarein O, Sheridan SC, Smith ET, Adams R. 2020. Examining trends in multiple parameters of seasonally-relative extreme temperature and dew point events across North America (Manuscript currently in peer review). Each dataset is organized as follows: The first two rows are column headers showing the latitude and longitude of the 18,661 land-based gridpoints (from the North American Regional Reanalysis dataset) in the study domain (23°N to 83°N, 46°W to 167°W). The first three columns are row headers showing date information (year, month, and day) for each day in the study period. The rest of the data are binaries (0 or 1) signifying whether each day is an extreme event day (1) or not an extreme event day (0) for each location. The four datasets (one for each type of extreme event) are in a single compressed (.zip) folder and each dataset/file is in comma separated value format (uncompressed size of each file is approximately 506MB). The research leading to the development of this dataset was supported by federal award number NA17OAR4310159, entitled “Developing extreme event climate change indicators related to human thermal comfort” from the National Oceanic and Atmospheric Administration’s Climate Program Office.
