I like Gov Brown, but I think this is the wrong approach to keep the satellites and databases. The satellites were launched for weather prediction, navigational aid. The further forward we can predict bad weather, the better we can re-route ships and planes, etc. If we can go far out enough we can apply this to farming. So we need the weather satellites to lower business costs, something Trump is supposedly in office to do.
Please note, there are multiple ways of predicting the weather, we can use a physical model of the environment, or a statistical model of the environment. Note that both are computer models. The statistical approach is not just what is the typical weather for this time of year and range. The statistical model is when similar conditions occur, these are the likely outcomes. This statistical approach requires the existing databases of weather conditions to predict the weather.
The physical model also requires the data,. As computers become faster, we can take more variables into account, creating better, more refined models that can predict further into the future.To validate these models we need historical data, ie if the model cannot predict weather conditions that have already occurred, then it is a bad model.
It is also a good idea to keep obsolete models. The reasons are two fold. First, it keeps you from repeating the same old mistakes. It also allows you to take a step back in the model if you find that when you add new variables that make your model better show that some of the variables you added in before were modeled wrong, or lead to a false adjustment due to "other variables" that you have not figured out yet.
Global warming, climate change are both issues that i believe to be real, but that discussion is separate from the need to maintain and update the existing databases and satellite infrastructure. It just makes good business sense. If someone uses that data for issues beyond immediate business needs, ie Global warming, it's their own business and does not change the need for the satellites.
