Interesting. So what I am looking for is probably an even more scaled down version? Or something that runs in the cloud with an api to upload my local measurements.
Hate to break it but one weather station wont improve a forecast? What are they supposed to do? Ignore the output of our state of the art forecast models and add an if statement for your specific weather station??
National weather institutions sometimes do this, since they don't have the resources to run a massive supercomputer model.
