[ ] A real-time weather forecast > Try again! A science configuration is more than just a forecast. 1. [x] A frozen package of mature science settings tested across timescales > Correct! A science configuration is a carefully tested and frozen package of settings. 1. [ ] A software update for LFRic > Try again! It's not just a software update. 1. [ ] A set of climate observations > No, but climate observations are important for evaluating science configurations. ## Which of the following is *not* one of the Momentum framework’s four core models? > hint: One of these is popular in the US, not the UK. 1. [ ] LFRic Atmosphere > Try again! LFRic Atmosphere is the atmospheric model in the Momentum framework. 1. [ ] NEMO > Try again! NEMO is the ocean model in the Momentum framework. 1. [ ] SI³ > Try again! SI³ is the sea ice model in the Momentum framework. 1. [x] WRF > Correct! WRF is not part of the Momentum framework; it's a different atmospheric model. ## What does GAL stand for in the GC configuration? > hint: The name contains two important parts of the Earth system. 1. [ ] Global Atmospheric Layer > Try again! Think about the components involved. 1. [x] Global Atmosphere Land > Correct! GAL stands for Global Atmosphere Land. 1. [ ] General Atmospheric Logic > Try again! That's not quite right. 1. [ ] Global Analysis Loop > Try again! That's not the correct term. ## What is the purpose of the OASIS coupler in GC configurations? > hint: Think of OASIS as a matchmaker for model components. 1. [ ] To simulate sea ice melting > Try again! OASIS couples the sea ice model with the atmospheric model but it does not simulate sea ice melting 1. [x] To couple the GAL and GOSI components > Correct! OASIS couples the GAL and GOSI components. 1. [ ] To visualize model outputs > Try again! Visualization is not OASIS's role. 1. [ ] To replace LFRic > Try again! OASIS does not replace LFRic. ## Which GC configuration was the last to use the Unified Model (UM)? > hint: The number is one higher than GC4. 1. [ ] GC3.1 > Try again! GC3.1 is earlier than the last UM-based configuration. 1. [ ] GC4 > Try again! GC4 is not the last UM-based configuration. 1. [x] GC5 > Correct! GC5 was the last configuration to use the UM. 1. [ ] GC6 > Try again! GC6 will be the first to use LFRic operationally. ## What is LFRic named after? > hint: He was a pioneer in weather prediction 1. look for the initials. 1. [ ] A famous climate model > Try again! LFRic is not named after a model. 1. [ ] Low-Frequency Radiative Instability Code > Try again! That's not correct. 1. [x] Lewis Fry Richardson, a British mathematician > Correct! LFRic is named after Lewis Fry Richardson. 1. [ ] A programming language > Try again! It's not a programming language. ## How are the GAL and GOSI components coupled? > hint: They need a little help from a friend called OASIS. 1. [ ] Intra-model coupling > Try again! Intra-model coupling is for atmosphere-land or ocean-sea ice pairs. 1. [x] Inter-model coupling via OASIS > Correct! They are coupled via OASIS, which is inter-model coupling. 1. [ ] Manual data transfer > Try again! It's not manual. 1. [ ] Shared memory execution > Try again! They don't share memory directly. ## Are GC configurations used only for climate projections? > hint: Think bigger - weather and climate are both in the mix. 1. [ ] Yes, only for long-term climate studies > Try again! GC configurations are more versatile than that. 1. [x] No, they are used across weather and climate timescales > Correct! GC configurations are used for both weather and climate. 1. [ ] Only for seasonal forecasts > Try again! They are not limited to seasonal forecasts. 1. [ ] Only for operational NWP > Try again! They are used for more than just NWP. ## What is the first GC configuration to use LFRic operationally? > hint: It's the highest number in the list. 1. [ ] GC4 > Try again! GC4 uses the UM, not LFRic. 1. [ ] GC5 > Try again! GC5 also uses the UM. 1. [ ] GC5-LFRic > Try again! GC5-LFRic is a research version, not operational. 1. [x] GC6 > Correct! GC6 will be the first operational use of LFRic. ## What are PEGs and CoGs? > hint: Not mechanical parts, but groups of people. 1. [ ] Types of model components > Try again! They are not model components. 1. [x] Evaluation and collaboration groups within the GC development process > Correct! PEGs and CoGs are groups that help evaluate and develop GC configurations. 1. [ ] Ocean modelling tools > Try again! They are not tools. 1. [ ] Coupling interfaces > Try again! They are not interfaces. ## What is the main advantage of the seamless modelling strategy? > hint: Seamless means smooth transitions - think consistency. 1. [ ] It reduces the need for ocean models > Try again! Seamless modelling is about more than just ocean models. 1. [x] It enables consistent modelling across timescales and spatial resolutions > Correct! Seamless modelling ensures consistency across different scales. 1. [ ] It simplifies data storage > Try again! Data storage is not the main focus. 1. [ ] It avoids the need for testing > Try again! Testing is still essential. ## What is the role of the GMED team? > hint: They're the brains behind GC development. 1. [ ] To run operational forecasts > Try again! Running forecasts is not their main role. 1. [x] To evaluate and develop GC configurations collaboratively > Correct! The GMED team focuses on evaluating and developing GC configurations. 1. [ ] To manage IT infrastructure > Try again! IT management is not their focus. 1. [ ] To publish climate reports > Try again! Publishing reports is not their main role. ## Why are the atmosphere and land models integrated into a single executable? > hint: They need to talk to each other every timestep. 1. [ ] To reduce memory usage > Try again! Memory usage is not the main reason. 1. [x] Because they are physically interconnected and exchange data every timestep > Correct! The atmosphere and land models are closely linked and need to exchange data frequently. 1. [ ] To simplify the codebase > Try again! Code simplicity is not the main reason. 1. [ ] To allow for manual tuning > Try again! Manual tuning is not the reason. ## How long is the typical development cycle for a GC configuration? > hint: It's how long it took to construct the Panama canal. 1. [ ] 6 months > Try again! The development cycle is longer than that. 1. [ ] 1 year > Try again! The development cycle is longer than that. 1. [x] Approximately 2 years > Correct! The development cycle is about 2 years. 1. [ ] 5 years > Try again! The development cycle is shorter than that. ## Regional model question placeholder. Maybe add more questions or replace some existing ones. > hint: Write a hint here. 1. [x] Option A > Correct! Write feedback here. 1. [ ] Option B > Try again! Write feedback here. 1. [ ] Option C > Try again! Write feedback here. 1. [ ] Option D > Try again! Write feedback here.
