Though Climate change is a vast topic but NOAA, METEOSAT and RSAT data may help to analyse some of the elements of climate.

there is no special satellite for CC. instead, rainfall, temperature, and RH trends might be used as indicators which can be downloaded from the following link:

Many Thanks 

there are two datasets: RSS &UAH.

Formerly there were discrepancies between them, but these have recently been resolved.

You may read online outdated comments concerning satellite drift errors, but these errors were corrected long ago, so now current satellite temperate estimates are consistent with radiosonde data.

Hi,

definitely, it depends on your resolution and your data. But in my opinion you can use METEOSAT, LandSat and.... , but if you want to trace historical data for climate change from past to now you can use other products such as APHRODTE,  TRMM, AgMERRA or CRU with different resolutions.

Best wishes,

Instead of trying to tease out climate change on a local scale, perhaps it would be easier to determine what factors previously were acted together to produce a climate stable-state in a particular area, prior to any recent climate change conditions.

For example in California we had regular rainfall between October and April each year, that originates from the Pseudomonas host tropical native forest trees growing in Indonesia and Malaysia, as does the India Monsoon originate from that area also each summer.  

So if you trace back the source of Mongolia's rainfall origins, you may find that some on-the-ground changes in distant lands are actually the main driver of what is viewed as climate change locally, like increases in local droughts.  

For California we have the cutting of tens of millions of acres of the tropical forests and converting them to oil palm farms, that were the source of our rainfall in the Pseudomonas bacteria living on their leaves over the last decade, which has caused a ten-year drought to engulf our State.

 Our fifth largest river, the Salinas, has not flowed to the ocean in three of the last four years, for example.  But if just looked at the climate change in California on the local scale, and not tracing back where our rainfall originates, we would miss the massive tropical forest changes occurring many thousands of miles away, that are driving the changes.
