University of Washington Experimental Surface Water Monitor for the Continental U.S.
Current percentiles for soil moisture, SWE and other variables with respect to the climatological period (1916-2004 for CONUS and 1926-2004 for Mexico). These update daily by 11-12 pm PST, and have a lag of 1-2 days. Roll the mouse over links below (or click) to see different maps . Note: SM & SWE maps are for daily values, whereas RO maps are for cumulative values.

Interpreting Satellite Images. The radiometers flown on satellites are not cameras. Moving mirrors make the radiometer view different regions of the earth.

NOAA satellites use Zulu Time or Coordinated Universal Time (UTC) as their time reference. The satellite images that appear on NOAA's Web sites are stamped in Zulu time. To make the conversion to your local time, see the chart below. Find your local time in the first column. If you are on Eastern Daylight Saving Time (EDT), you would use the second column to find your Zulu Time/UTC.

Latitude/Longitude Distance Calculator
Enter latitude and longitude of two points, select the desired units: nautical miles (nm), statute miles (sm), or kilometers (km) and click Compute . Latitudes and longitudes may be entered in any of three different formats, decimal degrees (DD.DD), degrees and decimal minutes (DD:MM.MM) or degrees, minutes, and decimal seconds (DD:MM:SS.SS).

SSEC - FAQ
The majority of satellite imagery that SSEC focuses on, such as GOES, NOAA polar satellites, Aqua/Terra, etc., is geared towards viewing Earth's meteorology, oceanography and climate and does not have the spatial resolution to see things like people or cars. For example, the MODIS instrument on the Aqua and Terra satellites has a resolution of 250 meters which means that it can't resolve anything smaller than that. However, the WisconsinView organization which operates here at SSEC does work with high resolution satellite imagery that could be of use for observing smaller scale objects/places on the ground. Specifically, WisconsinView maintains a free online archive of civilian public domain color satellite imagery and aerial photos of Wisconsin with spatial resolutions ranging from 15cm (6-inch) to 250m (273yds).
Now that I’ve *finally* finished the series on how to meet or beat most of Google Earth Plus’s features without paying for it, here’s a one-post set of links to all the posts in the series. As part of the spreadsheet import, Google Earth Plus will let you geocode 100 addresses, but free options let you geocode thousands of addresses per day. A post about GPS TrackMaker, totally free software for GPS export/import to Google Earth, file conversion, track editing and more. A link to the DestinSharks.com description of Google Earth Voyager, a free program for automated caching of Google Earth data for offline use.
