How do we derive the Earth's yearly mean temperature?

In summary, deriving the Earth's yearly mean temperature involves collecting temperature data from various sources, including weather stations, satellites, and ocean buoys. This data is then averaged over different regions and times to account for seasonal variations and geographical differences. The process also includes adjustments for biases and anomalies to produce a consistent global temperature record. The final mean temperature is calculated by aggregating these adjusted values to reflect the Earth's overall climate trends over the year.

I'm new to this.
I would like to know how we derive the earth's yearly mean temp.
I assume there are thermometers all over the world, buy how many and how are they connected, how frequently are temps taken?
Stuff line that

Oh, got it (sort of).

What have you found so far in your Google searching for how global temperatures are measured and communicated? It was probably harder in the pre-Internet days, but there must be some sort of standard temperature monitoring stations all linked up via the Internet now, no?

You have effectively restated my question. Do you know the answer?

Nope, but I know how to use Google. What have you found so far?

(we prefer that folks show their efforts on their questions before we try to help out)... :wink:

I'm not in class.

I thought people who frequented forums knew something about the subject and would answer questions.

Guess not.

Of course we do and we can. But part of PF's mission is to help folks to learn how to learn. We don't spoon-feed folks here. Please do at least a little Google searching and post what you find. If you have questions about what you have found, we are happy to help you with those questions.

You have mistaken this for a Q&A forum where you DO just ask and get answered. We are much more interested in helping people learn how to learn. Spoon feeding answers is boring. As @berkeman said, we expect some effort on your part. Again, not a Q&A forum.

If you just want an answer, learn to use Google.

New PF user has been reminded to do their own research before asking for help in the forums
This is not a "Q and A" forum? Really?

Well, you have asked me questions and I have answered them, and that's "Q and A".

So, you can ask questions and get them answered but I can't.

This forum is useless.

By the way, telling me to learn to use google is a snide insult. Why do you go there?

Suggesting that you actually use Google to search on your question before asking volunteers to spend their time to do that for you? Who is insulting whom?

This thread is done. If you have trouble with your Google search, send me a PM. Lordy.

FAQ: How do we derive the Earth's yearly mean temperature?

What is the Earth's yearly mean temperature?

The Earth's yearly mean temperature is an average value that represents the overall temperature of the Earth over the course of a year. It is calculated by taking temperature readings from various locations around the globe and averaging them to provide a comprehensive picture of the planet's climate.

How is the Earth's yearly mean temperature calculated?

The Earth's yearly mean temperature is calculated by collecting temperature data from a network of weather stations, satellite observations, and ocean buoys. These measurements are then averaged, often using a weighted system that takes into account the geographical distribution of land and sea, to produce a global average temperature.

What data sources are used to determine the yearly mean temperature?

Data sources for determining the Earth's yearly mean temperature include ground-based weather stations, satellite data, ocean buoys, and climate models. These sources provide a comprehensive set of temperature readings that are essential for accurate calculations.

Why is it important to know the Earth's yearly mean temperature?

Understanding the Earth's yearly mean temperature is crucial for assessing climate change, predicting weather patterns, and informing environmental policies. It helps scientists and policymakers monitor trends in global warming and its potential impacts on ecosystems and human societies.

How does climate change affect the Earth's yearly mean temperature?

Climate change can lead to an increase in the Earth's yearly mean temperature due to the accumulation of greenhouse gases in the atmosphere. This results in more heat being trapped, which can cause shifts in climate patterns, increased frequency of extreme weather events, and changes in ecosystems.
