MODIS Rapid Response Site MODIS-Atmos Site NASA’s Visible Earth NASA’s Earth Observatory NASA Earth Observations (NEO) MODIS Today World View A Brief Tour of Some Useful Image Archives 2

MODIS Rapid Response Site time-data/rapid-response MODIS only image archive which is easy to search. Quick posting of new MODIS images. Links to data used to generate MODIS images. Collections of images by region and by association with ground based instruments NASA’s Visible Earth A tremendous archive of images and animations from and about many sensors. Search results can be too large to browse through unless many conditions are added to the search. NASA’s Earth Observatory Site designed for outreach and education. Images and stories of Earth Science phenomena are linked. Subscriptions to newsletters to keep track of recent stories and Natural Hazards. NASA Earth Observations (NEO) Site designed for outreach and education. Can explore several remote sensing products with an easy to use interface. The ability to quickly produce high quality graphic images from the site. The ability to quickly create products that can be mapped onto Google Earth. 3

MODIS NRT Data at LANCE data/rapid-responsehttps://earthdata.nasa.gov/data/near-real-time- data/rapid-response MODIS subsets -> FAS Good GIS base layers 4

Example: Rim Fire at Yosemite NP Click on USA 1 subset Set date to Aug 30 Select Terra or Aqua View 2 km imagery Add vector options: fires+coast+borders View previous and next days View 250m/500m/1km images

For GIS Operations Choose 250 m resolution Download JPG image with ancillary files (.zip), or Download GeoTIFF file If selected, vector options will become part of the image, not separate layers

The site includes a searchable archive of “Image of the Day” Site #2 NASA’s Earth Observatory 7

NASA’s Earth Observatory is intended to be an educational site for the general public with an interest in Earth Science. Feature articles explaining Earth Science issues and phenomena The site includes a searchable archive of “Image of the Day” 8

A simple search using “fires” “California” returns 63 pages of results. You can use the drop down menu to choose a section of the site to search to reduce the number of results. Site sections include: Image of the day Features Natural Hazards News Blogs 9

You can browse the archive by broad topic categories 10

You can browse within a topic by subtopic or by date. Natural Hazards Section 11

One very nice feature of this site is the option to subscribe to any of several news letters. For example, if you wanted to keep track of the most recent news on volcanic eruptions, you would subscribe to the Natural Hazards Daily 12
