NASA has an incredible tool using which you can see two decades of weather activity of the earth. Using this NASA worldview tool you can see how the weather has changed from 2000 to 2018.
MODIS (Moderate Resolution Imaging Spectroradiometer)
The imagery comes from NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA’s Terra and Aqua satellites, which launched in 1999 and 2002, respectively, observing weather patterns on Earth for almost 20 years. MODIS became operational in 2000, and ever since, the instrument has provided imagery through NASA’s Global Imagery Browse Services (GIBS), which can be viewed in NASA’s Worldview tool.
Using the Worldview interactive interface, you can explore satellite imagery easily in your web browser. You can even specify within Worldview to see everything from fires to dust storms. You can see all the major events for this past 2 decades by just sorting events.
GIBS provides access to more than 600 satellite imagery products covering every part of the world. Worldview pulls imagery from GIBS and allows users to interactively overlay all of these data products on top of a MODIS global base map from Terra or Aqua. Worldview users can even create data animations at the touch of a button and easily share imagery. Both GIBS and Worldview are part of NASA’s Earth Observing System Data and Information System (EOSDIS), which provides end-to-end capabilities for managing Earth-observing data.
Watch the video which NASA have created by using 2 decades of data by using MODIS in just 2 mins.
Satellite images of weather patterns are helpful for a number of reasons, and in 2016 and 2017, they allowed researchers to observe the California wildfires, as you can see in the video above. Also seen in the video is how this technology allows us to observe air quality and dangerous levels of smoke and haze in India.
Isn’t this a great use of technology, where you are able to see all the weather condition for past 2 decades at your fingertip. Just use the worldview tool and see how the weather has changed and what has caused the weather changes.
