From Space

Here’s an image of South Africa from space, via NASA’s Modis/Terra satellite. Modis is Moderate Resolution Imaging Spectroradiometer (I know – it doesn’t quite work, does it?)

With its sweeping 2,330-km-wide viewing swath, MODIS sees every point on our world every 1-2 days in 36 discrete spectral bands. Consequently, MODIS tracks a wider array of the earth’s vital signs than any other Terra sensor. For instance, the sensor measures the percent of the planet’s surface that is covered by clouds almost every day.

That’s conveniently just about the width of South Africa, allowing this sort of shot:

You can see that we were having a wonderful day in Cape Town (although I spent it in a lab, in a car and at Tygerberg Hospital, rather than chilling at a bar by the beach).

I’m hoping to be able to get a repeat image to compare when the cold front comes through on Thursday evening (it’ll be dark, I know) and through Friday morning.
