Back to opportunities | Category Index
These are the intended use-case/justification for one or multiple variable groups. Opportunities are linked to relevant experiment groups. Identifying opportunities helps to provide a structure to map variables against requirements. Each opportunity description will convey why this combination of variables and experiments is important and how they contribute to impact.

| description | This opportunity is aimed at leveraging CMIP data for assessments of hydrological processes, water resources, and freshwater systems (i.e., rivers and estuaries, lakes and inland water bodies, groundwater, snowpack, permafrost, and glaciers). In addition to their application as input data for related modeling exercises (e.g., hydrology, lake, or glacier models, etc.), these sets of daily and monthly variables will be useful for (1) assessing the usability of Earth system models for water resources applications, (2) evaluating whether these processes/systems are adequately represented in the modeling frameworks, and (3) offering opportunities for model intercomparisons across these topics. |

| expected_impacts | There are multiple use cases for these variables: (1) Variables related to lakes (SST/lake surface water temperatures, lake fraction, lake depth, etc.) have been used in studies related to lake-atmosphere interactions [[1](https://journals.ametsoc.org/view/journals/clim/34/12/JCLI-D-20-0751.1.xml) and [2](https://journals.ametsoc.org/view/journals/atsc/79/5/JAS-D-21-0249.1.xml)] and usability of CMIP models for large lakes [[1](https://www.sciencedirect.com/science/article/pii/S0380133021000289)]. (2) Surface runoff variables used to assess model hydrological sensitivity and improve streamflow projections (e.g., [1](https://www-nature-com.cuucar.idm.oclc.org/articles/s41558-019-0639-x#Sec7)] (3) Snow water equivalent and soil moisture to assess terrestrial water storage anomalies [e.g., [1](https://journals.ametsoc.org/view/journals/clim/34/20/JCLI-D-21-0021.1.xml)] (4) Water budget variables are important for assessments related to water availability and security, and hydrometeorological extremes (floods and droughts) (5) A range of variables (e.g., precipitation, PET, etc.) have applications for hydrological simulations using bucket-type/watershed models. |
| justification_of_resources | These variables are of interest to a large number of applications related to water resources and will allow comprehensive assessments for regional hydroclimates. The opportunity is also relevant for climate impact assessments on freshwater resources and water availability. |
