Because it's a waste of money. You don't need satellites to measure CO2 levels. Ground based measurements work perfectly fine, which is where air is densest. These satellites are supplementary and are fairly imprecise in measuring CO2 as they look at reflected sunlight from the surface. Note that the satellite can't measure through clouds, which is 2/3 of the atmosphere at any given time.
This is a satellite you probably never heard about before but you were moved by an overemotional headline that a journo used to manipulate your pretenses.
- EdwardDiego 1y agoSo... how many ground based CO2 stations are there? And do they have the same coverage as a satellite? Also, why do we need weather satellites when ground wx stations work perfectly fine?
- chrisco255 1y agoThere are many, but the most important one is Mauna Loa. CO2 is well mixed in the atmosphere. It has to be or plant life would suffocate and die (remember CO2 is their O2). Just like Oxygen is well mixed and evenly distributed around the planet. A ground measurement that is sufficiently isolated from forests or cities that could have localized effects is ideal. Muana is considered ideal because it sits out in the Pacific ocean on a remote island of Hawaii. https://www.co2.earth/22-co2-now/121-mauna-loa-co2 https://www.co2.earth/22-co2-now/121-mauna-loa-co2 For list of stations besides Mauna Loa: https://gml.noaa.gov/dv/site/ https://gml.noaa.gov/dv/site/
