The Great Lakes ice cover was from 15% to 18% this week, compared with about 67% a year ago, the National Oceanic and Atmospheric Administration says Why 8 … As shown in this imagery, Lake Erie has the greatest amount of ice cover (about 92 percent). Water Multisensor Analyzed Sea Ice Extent. NASA's Aqua satellite captured this image of the lakes on the early afternoon of Feb. 19, 2014. Water A downward trend since the 1970s in the annual maximum extent of Great Lakes ice cover, which reaches a maximum every year during late winter and early spring, spells trouble for the Great Lakes ecosystem and the people who rely on it.. NOAA’s daily analysis of lake ice cover on January 30, 2020, found just 6.7 percent of the lakes covered by ice. Sea and Lake Ice. Caption by Kathryn Hansen.

This image was capture on February 21, 2014 by NASA's Aqua satellite. Great Lakes Ice Cover Observations Lake Erie Vertical Temperature Mooring (2017) links to NCEI archive Lake Huron Vertical Temperature Mooring (2012-2019) links to NCEI archive Saturday, the Great Lakes peaked at 80.87% ice cover. Both Amadjuak and Nettilling lakes show a range of ICD from 11 days shorter to 15 and 18 days longer, respectively. GeoColor. This color-enhanced imagery from the Suomi NPP satellite's VIIRS instrument shows ice cover on the Great Lakes on February 12, 2018. Lake ice and snow cover on land appear gray-white, while the relatively warm, non-frozen lake water appears nearly black. GLERL conducts research on ice cover forecasting on two different time scales: short-term (1-5 days) and seasonal. Project: Lambert, Spheroid Clarke 1866. Images updated every 5 minutes. The map, known as the Great Lakes Surface Environmental Analysis, is a composite of data taken from NOAA satellites orbiting the earth’s poles and radar scans of the lakes by the National Ice Center. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired the top image of ice cover on North America’s Great Lakes on March 17, 2015. Figure 4 provides lake-wide ice duration anomalies for selected large lakes in Canada and Russia for the 2004-18 period. NASA's Aqua satellite captured this image of the lakes on the early afternoon of Feb. 19, 2014. As of February 11, 69.1 percent of the Great Lakes were ice covered, according to data from NOAA's Great Lakes Environmental Research Laboratory. Image of the Day The study also showed that ice cover on the lakes is highly variable and difficult to predict. For example, early and persistent cold air temperatures during the winter of 2013-2014 brought record-high ice cover to most of the Great Lakes, reaching 88 percent coverage. Northern hemisphere sea ice coverage for the last four weeks, updated daily. Snow and Ice, Moderate Resolution Imaging Spectroradiometer, NASA Goddard Space (Credit: National Weather Service) (Credit: National Weather Service) Lake Erie Satellite image of ice … Great Lakes ice cover facts since 1973. Snow and Ice Aqua MODIS images courtesy Jeff Schmaltz, LANCE/EOSDIS MODIS Rapid Response Team at NASA GSFC. Atmosphere Snow and Ice Lake Erie is usually the first to freeze over because it is shallower than the other Great Lakes. IMS snow and ice products. How to read an ice chart. Get Started We're launching the Smart Great Lakes Initiative as part of our strategic plan for 2020-2025. These lakes have shown positive ICD anomalies for 7 of the last 14 ice seasons, with most of the longer ICD anomalies in the past six seasons. Ice cover on the Great Lakes peaked at more than 80 percent in 2014 and again in 2015, marking the sixth such occurrence in four decades. This image, acquired by the Moderate Resolution Imaging Spectroradiometer on NASA's Aqua satellite, shows the Great Lakes on Feb. 19, 2014, when ice covered 80.3 percent of the lakes. True Color daytime, multispectral IR at night 8 Dec 2020 - 18:31 UTC. Average date ice cover >or= 10%: A sample of the digitized total ice concentration for the Great Lakes. On that day, ice covered 55 percent of the lakes, according to the NOAA Great Lakes Environmental Research Laboratory. Satellite data shows a generally downward trend in Great Lakes ice cover from 1972 to the present, thanks largely to the general increase in winter temperatures over the same time period. A 2012 study in the Journal of Climate by scientists at NOAA's Great Lakes lab, which included data from MODIS, found that winter season ice cover on Lake Superior has decreased 79 percent from 1973 to 2010. Recent daily ice edge files around Alaska and within the Great Lakes, in GRIB format. Image of the Day Animation Loop; 300 x 300 px, (JPG, 86 KB) ... Snow/Ice - Near IR 8 Dec 2020 - 18:31 UTC. GREAT LAKES ENVIRONMENTAL RESEARCH LABORATORY. Occasionally the ice cover is be extensive enough or thick enough to interfere with commercial shipping. In this wintertime shot, the lakes are relatively ice-free, except for Lake Erie. These links to the Great Lakes Coastal Forecasting System -- Nowcast/Forecast pages include: current observed ice cover, wind, and air temperature; model-derived ice thickness, ice velocity, vessel icing, surface currents, and water temperature. About GeoColor. Percent Ice Cover for all lakes: 51.42%. Ice Edge GRIB Files. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired the top image of ice cover on North America’s Great Lakes on March 17, 2015. 11.5% ice coverage in 1998, a strong El Niño year. Color-enhanced images like this one help highlight visual differences in ice thickness, including cracks on the ice surface. Warm air prevailed in the 2019-2020 winter season, preventing much ice from forming on the lakes. Sea and Lake Ice. Against the backdrop of snowy ground appear the deep blue waters of the Great Lakes and nearby water bodies. Great Lakes ice cover typically begins to peak from late February into the start of March. Great Lakes ice cover continues to increase. The seasonal cycle of ice cover was constructed for all the lakes, including Lake St. Clair. 9.5% ice coverage in 2002 is the lowest on record. The average maximum ice extent since 1973 has been about 50 percent. As you can see, there is a lot of ice … The extreme ice cover in 2014 (92.5%) and 2015 (88.8%) were the first consecutive high ice cover years since the late 1970’s. Water Weekly ice coverage in that period of time is typically 35 to … Total ice area for all Lakes: 130,712 square km. Clear skies, thanks to high pressure over the region, reveal lake ice and snow cover on the ground in remarkable detail. Typical ice condition charts.
