We recently came across an interesting set of animations on YouTube. They are:
- Monthly Water Vapor (Aqua/MODIS) 2002-2013
- Monthly Albedo 2000-2013
- Monthly Solar Insolation 2006-2013
- Monthly Sea-Surface Temperature Anomalies 2002-2011
- Monthly Carbon Monoxide (Terra/MOPITT) 2000-2013
The data for the animations comes from NASA Near Earth Observation data. We mentioned this site in 2007, but there is a lot more data available than there was then. We count 71 different datasets, many of which include daily data for most of the world and fairly comprehensive monthly data. We had a look at the Average Cloud Cover map earlier this year.
The YouTube animations above only go up to 2013, but the data is actually available almost to the current date. All the maps can be viewed in Google Earth. Just look to the right of the map under “File Type” and select “Google Earth” and then select the highest resolution available and it will download as a KML file viewable in Google Earth.
Outgoing longwave radiation – September 2015
It is also relatively easy to download a series of images and create an animation similar to the YouTube videos. For example, we created this KMZ file
that shows an animation of Solar Insolation for the past year. For best results, click the spanner icon on the timeslider and make sure ‘loop animation’ is ticked. To run the animation click the icon that looks like a combined clock and a play button
