Louis Nguyen NASA Langley Research Center J. Walter Strapp Met Analytics, Inc. Sea ice in the Arctic: 2014 on left, versus 2019 on right. Offering finer detail than satellite imagery, the National Air Photo Library is a comprehensive historical archive and public reference centre. Image: Satellite image of Algonquin Park taken on May 1, 2020 showing no visible ice at Lake Opeongo (click to enlarge). The Ice Service analysts study the current conditions primarily via remotely sensed data and provide ice charts, ice-edge information and an overview of the sea surface temperatures. Other, scattered records of Arctic sea ice date back to the mid-1700s, when sailors kept notes on Northern Hemisphere shipping lanes. The visible satellite imagery is essentially a snapshot of what the satellite sees, unlike Infrared (IR) satellite imagery, which depicts the temperature of the clouds. Great Lakes MODIS Imagery. Near real-time and archived high resolution, true color MODIS images over the USA acquired from the NASA Terra and Aqua satellites. Sea Ice Extent Using the latest satellite observations, NASA researchers and others report that the Arctic is still on “thin ice” when it comes to the condition of sea ice cover in the region. The bold line is the most frequently used route if ice conditions permit. In this capacity, GLERL obtains, produces, and delivers environmental data and products for near real-time observation of the Great … Analysis and Automated Detection of Ice Crystal Icing Conditions Using Geostationary Satellite Datasets and In Situ Ice Water Content Measurements 2019-01-1953 Recent studies have found that high mass concentrations of ice particles in regions of deep convective storms can adversely impact aircraft engine and air probe (e.g. Ice that is 6 years old or older shows an even more dramatic decrease in 2008 compared to average conditions. Satellite Observations for Detecting and Forecasting Sea-Ice Conditions: A Summary of Advances Made in the SPICES Project by the EU's Horizon 2020 … 2. 4/29/20: Satellite imagery shows some of the shorefast ice on the north side of Kuskokwim Bay has broken off on the afternoon/evening of April 28th. Sea ice begins as thin sheets of smooth nilas in calm water (top) or disks of pancake ice in choppy water (2 nd image). Individual pieces pile up to form rafts and eventually solidify (3 rd image). Example of ERS SAR image from southern Kara Sea (11. New images will be posted soon. Satellite passive microwave sea-ice concentration data set inter-comparison for Arctic summer conditions Stefan Kern1, Thomas Lavergne2, Dirk Notz3, Leif Toudal Pedersen4, and Rasmus Tonboe5 1Integrated Climate Data Center (ICDC), Center for Earth System Research and Sustainability (CEN), Landsat satellite image showing ice roads used for trucking on Feb. 24, 2015 compared to when the lakes are unfrozen in the warmer months. In 2018, the summer extent was the sixth lowest and the winter extent was the second lowest in the satellite record (1979-2018). Titan is the largest moon of Saturn and the second-largest natural satellite in the Solar System.It is the only moon known to have a dense atmosphere, and the only known body in space, other than Earth, where clear evidence of stable bodies of surface liquid has been found.. Titan is one of six gravitationally rounded moons from Saturn, and the most distant from Saturn of those six. November 1994) in the beginning of the ice season. As reported in our previous post, sea ice extent averaged for October 2020 was the lowest in the satellite record.While extent increased through November as part of the annual cycle of autumn and winter growth, the November average extent of 8.99 million square kilometers (3.47 million square miles), ended up as second lowest in the satellite record for the month, just above 2016. Over time, large sheets of ice collide, forming thick pressure ridges along the margins (4 th image). Figure 2. Abstract. Unreasonably frequent reloading or "hotlinking" of these images into outside web pages adversely affects NOAA's ability to serve the public and is forbidden.Violation of this policy may be cause to temporarily block access to this site or pursue legal action in response to a denial-of-service attack on a Federal government computer. Ice age is a good indicator of general ice thickness, with older ice thicker on average than younger ice. If you know the ice conditions around Lake Simcoe and surrounding lakes please share with others. Discover more than 6 million aerial photographs covering all of Canada dating back to the 1920s. Current Ice Cover Conditions Coastwatch and GLSEA. For sea-ice product development and validation, a wide variety of in situ snow and sea-ice data was During 2018 and 2019 the ice out date for Lake Opeongo was May 10. MODIS True Color Images of the Great Lakes (by lake) More information can be found at the World Meteorological Organization (WMO) document-574: Sea-Ice … MODIS Satellite Current Ice Conditions Great Lakes Surface Environmental Analysis - NOAA Coastwatch Great Lakes Concentraion & Thickness Combined Chart . Satellite photos show how pitiful ice cover is in the Arctic right now. Baltice.org is a single access point to reliable and up to date information related to winter navigation in the Baltic Sea area. Thankfully, two teams of scientists from City College of New York and George Mason University had been working on PGGR products to monitor and track ice and flooding conditions using data from the NOAA/NASA Suomi NPP satellite, the flagship satellite in … We report on results of a systematic inter-comparison of 10 global sea-ice concentration (SIC) data products at 12.5 to 50.0 km grid resolution from satellite passive microwave (PMW) observations for the Arctic during summer. Baltice.org is a single access point to reliable and up to date information related to winter navigation in the Baltic Sea area. Although television pictures from Earth satellites have been used for over ten years to detect major sea ice features, direct photo-interpretation methods have been supplemented with a … There was the dearth of ice in the Bering Sea through the 2017/18 ice growth season. (Credit: USGS/Google Earth) Modis image for Great Lakes. GOES-16 imagery during the afternoon of Feb. 1, 2019. The Arctic sea ice cover continues the declining trends in the summer maximum and winter minimum extents. Air photos. This satellite image of the ice around Kugluktuk, Nunavut is from Nov. 1. Global air temperature records date back to the 1880s and can offer a stand-in (proxy) for Arctic sea ice conditions; but such temperature records were initially collected at just 11 locations. Satellite imagery captured a cool image Friday afternoon on Lake Michigan, where a ship could be seen cutting through the ice. While late March to early April is historically when the Bering Sea reaches its maximum ice extent, these two images from NOAA’s polar orbiting satellites show the stark contrast between what we’ve typically seen in the region versus what could soon be considered the new “normal.” On April 1, 2014, Suomi-NPP captured the image on the left, which shows much of the Bering and Ice Climatology. Image: noaa By Mark Kaufman 2019-04-02 17:59:18 UTC. New Products of Sea-Ice Conditions New sea-ice products developed in SPICES are based on a wide variety of Earth Observation (EO) data obtained from multiple satellite sensors, and numerical weather prediction (NWP) model data. Radar-based satellite imaging is a cost-efficient solution for frequent coverage because overpass times are not affected by cloud cover and weather conditions. Satellite Vidicon Data for Delimiting Sea Ice Conditions E. PAUL McCLAINl ABSTRACT. Go Back to ASIP CoastWatch is a nationwide National Oceanic and Atmospheric Administration (NOAA) program within which the Great Lakes Environmental Research Laboratory (GLERL) functions as the Great Lakes regional node. You can submit your information: ice thickness, distance from shore, exact or approximate location on the map, location of dangerous spots; pressure cracks, attach pictures, YouTube video to your ice report. Given variations in winter and spring conditions, the ice out dates for Lake Opeongo have ranged from March 29 (2012) to as late as May 15 (1972). The AMSR-E instrument on NASA's Aqua satellite provided the data for these images.
