Did you realize that the sea surface temperature affects the Earth’s atmosphere? Not only can ocean temperatures contribute to the study of global warming, but they also can influence the formation of major storm events. Interestingly, a lot of what we know about how our oceans change comes from information gathered by satellites in our planet’s orbit. These satellites collect data on the amount of light the oceans emit and reflect to keep track of surface temperatures through ocean-color radiometry. And as you likely would expect, proper calibration services, including the detection equipment, is crucial.
The enormous amount of data involved is delivered from multiple satellite sensors over decades of time to the National Oceanic and Atmospheric Administration’s Marine Optical Buoy (MOBY), an automated radiometric system bobbing in the waters of the Pacific Ocean off Hawaii.
Of course, the instruments and data-collection system on MOBY itself has to be thoroughly characterized and calibrated, a complicated job for many reasons. Radiometric cross checks help provide robust traceability to the International System of Units (SI). What’s more, a three-month-long rotation of duplicate systems makes it possible to perform scheduled maintenance and repairs on MOBY.
While MOBY has long exceeded its expected lifespan, it continues to provide critical data and is expected to keep doing so for the foreseeable future. The fact that it still can provide accurate data is due to the rigorous calibration efforts employed by the buoy’s caretakers.
Calibration is of vital importance when dealing with your sensitive data. Therefore, it makes sense to ensure your technology is properly calibrated.
