Program for Climate Model Diagnosis and Intercomparison is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Program for Climate Model Diagnosis and Intercomparison rather than just read about it. In short: The Program for Climate Model Diagnosis and Intercomparison (PCMDI) is a program at the Lawrence Livermore National Laboratory in Livermore, California. Livermore is in the San Francisco Bay Area in the United States.

Key takeaways

Program for Climate Model Diagnosis and Intercomparison belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Program for Climate Model Diagnosis and Intercomparison to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Program for Climate Model Diagnosis and Intercomparison from memory before moving on to harder problems.

Reference excerpt

The Program for Climate Model Diagnosis and Intercomparison (PCMDI) is a program at the Lawrence Livermore National Laboratory in Livermore, California. Livermore is in the San Francisco Bay Area in the United States. It is funded by the Regional and Global Climate Modeling Group (RGCM) and the Atmospheric System Research (ASR) programs of the Climate and Environment Sciences Division of the United States Department of Energy.

Main activities The main goal of PCMDI is to develop improved methods and tools for the diagnosis and intercomparison of general circulation models (GCMs). PCMDI is the canonical resource for a number of model intercomparison projects, including the Atmospheric Model Intercomparison Project (AMIP), Coupled Model Intercomparison Project (CMIP), Seasonal Prediction Model Intercomparison Project (SMIP), Aqua-Planet Experimental Project (APE), and Paleoclimate Modelling Intercomparison Project (PMIP). PCMDI is also developing the Cloud-Associated Parameterizations Testbed (CAPT) and is involved with other research and innovations that will help with the diagnosis, tweaking, and intercomparison of models.

Reception The model intercomparisons run by PCMDI are used in the Intergovernmental Panel on Climate Change (IPCC) reports, such as in Chapter 8 of the Working Group I report for the IPCC Fourth Assessment Report. On April 6, 2009, the American Meteorological Society held a meeting in Bethesda, Maryland to celebrate the twentieth anniversary of the operation of the PCMDI. The meeting summary was published in the Journal of the American Meteorological Society in May 2011.

Worked examples

Example 1 — a first encounter with Program for Climate Model Diagnosis and Intercomparison

Start with the simplest possible case. Write down what Program for Climate Model Diagnosis and Intercomparison claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Program for Climate Model Diagnosis and Intercomparison before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Program for Climate Model Diagnosis and Intercomparison ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Program for Climate Model Diagnosis and Intercomparison

In research: Program for Climate Model Diagnosis and Intercomparison appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Program for Climate Model Diagnosis and Intercomparison in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Program for Climate Model Diagnosis and Intercomparison is common in secondary-school and first-year university syllabi. It links to neighbouring topics Climate modeling, Climatology stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Program for Climate Model Diagnosis and Intercomparison outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
