The best pictures of thunderstorms, tornadoes and other extreme weather condition will be featured on the NASA Precipitation Measurement Missions websites at pmm.nasa.gov and www.nasa.gov/GPM, the space agency said.
Images should be in JPEG (.jpg) format in as high a resolution as possible with as much accompanying data as the user is comfortable providing, NASA said, including possibly name, affiliation (school, community group, etc.), location where the photo was taken and any other interesting details about the photo.
NASA is reminding entrants to be safe and not take extreme chances when shooting extreme weather.
Submissions of photos, which can be from any time period, will be accepted through Sept. 18.
Submissions can be made at the competition website, http://www.flickr.com/groups/gpm-extreme-weather/.
NASA's Global Precipitation Measurement mission is an international satellite mission that studies Earth's water and energy cycles.
