The circled area has only reached the melting point a few times in the early season. The team is evaluating the need for a mid-season correction.Ĭredit: National Snow and Ice Data Center/T. The gray lines and bands depict the average daily melt area for 1981 to 2010, the interquartile range, and the interdecile range.

The bottom graph shows daily melt area from April 1 to June 15, 2023, with daily melt area for the preceding four years, plus the record high year of 2012. The top right map illustrates the difference from the 1981 to 2010 average melt days for the same period. The top left map illustrates the cumulative melt days on the Greenland Ice Sheet for the 2023 melt season through June 15. We post analysis periodically as conditions warrant.Ĭlick an image for a high-resolution version.įigure 1. Get daily satellite images and information about melting on the Greenland ice sheet. Occasional short-term delays and data outages do occur and are usually resolved in a few days. However, visitors may notice that the date on the image is occasionally more than one day behind.

The daily image update is produced from near-real-time operational satellite data, with a data lag of approximately one day.

The daily image update isn’t current why? Read about the data and other problems which occasionally occur in near-real-time data. We are working to improve the ice sheet mask. This issue does not affect trends for the entire ice sheet. This is a false melt signal from seasonal snow and patchy ice areas, where our method of determining surface melting does not work. Note that the northeast coast (northern Peary Land and Kronprince Christian Land) is showing erroneous melt pixels. The Cumulative Melt Days image (right) shows the total number of days that melt occurred, year to date.Īreas along the coast are masked out because the satellite sensor’s resolution is not fine enough to distinguish ice from land when a pixel overlaps the coast. The Daily Melt image (left) shows where the surface of the Greenland Ice Sheet showed melt on that day. Not every station reports every day, and some stations never report certain values.The Greenland melt images here are updated daily, with a one-day lag. Information from the NCDC may be incomplete. Weather data collected from the National Climatic Data Center Global Surface Summary of Day. Looking forward? See the famous Old Farmer's Almanac long-range weather predictions. But also there are personal reasons for example, knowing about typical weather is helpful for vacation travel, planning an outdoor event or wedding, and planning for outdoor activities such as sailing (think wind!). How do you use weather history? There are so many practices uses for business from developing informed business forecasts to understanding road and accident conditions. The Old Farmer's Almanac weather history tool provides access to weather reports from over 1,300 weather stations in cities across the United States and Canada, reporting on past temperatures, precipitation, snow, pressure, dew point, and wind speeds. Interested in weather history? Access weather history data for dates going back to 1945! It's both useful and fun-whether you're planning a trip or just want to know the weather on a special date.
