LTAR meteorology and cameras data including the solar eclipse on August 21, 2017. Data is preliminary, have not been reviewed, and are subject to revision.
The red circles on the map are the Long-Term Agroecosystem Research (LTAR) sites that have provided weather, solar energy, and/or photographs.
The blue line marks the center of the total eclipse path. The sun icons show the location of the total eclipse at 10 minute intervals, displayed in local daylight saving time.

The table provides information about the LTAR sites sorted so those closest to the total eclipse path are first. Obscuration is the maximum percent of the sun covered by the moon for that location. 100% means total eclispe and 0 would be no eclipse at all. The Maximum Eclipse is the local time for maximum obscuration. These values were obtained from NASA's Total Solar Eclipse Interactive Map
The Site Name links to information about that specific site in the LTAR Research Data Overview
The chart displays air temperature and solar energy values every 15-minutes for August 21st. Since these are averages, they do not represent the extremes. For example, 2-minutes of total eclipse darkness would be averaged with 13 minutes of partial eclipse before/after the period of totality.
Solar energy sensors vary between sites, so not all sites will have data for the following:
Many of the LTAR sites participate in the PhenoCam network contributing fixed photos (typically at 30 minute intervals) that are used to monitor seasonal changes in the greenness of the plants.
These photos during the eclipse period may show some lighting changes. However, the changes may be subtle and difficult to see in the photographs, expecially as camera exposures may vary.
