Soil Moisture Memory | Coupling Metrics
http://www.coupling-metrics.com/soil-moisture-memory
How to Use it. Assesses the ability of soil to retain its moisture state, or more specifically the time it takes for soil moisture to decay to a condition beyond 1/e. Quantifies the time it takes for soil moisture to lose information of its initial state, meaning the time it takes for the lagged autocorrelation of soil moisture to fall below its e. Be cautious when comparing soil moisture memory across different sites when using in-situ data because measurements may have been taken at various depths or w...

Heated Condensation Framework | Coupling Metrics
http://www.coupling-metrics.com/heated-condensation
How to Use it. Assesses the atmospheric background state with respect to convective initiation using. Convection can also be identified as having been triggered due to local surface forcing when. Equals zero. Additionally the amount of surface sensible heat flux necessary for triggering convection assuming no additional moisture inputs is defined by. Representing the strictly heat pathway. Conversely the moisture pathway for triggering is quantified by. And Figures 5-8 from Part II. Translate to drier, m...

Terrestrial Coupling Index | Coupling Metrics
http://www.coupling-metrics.com/terrestrial-coupling-index
How to Use it. Determines the magnitude of coupling between soil moisture and surface fluxes using statistical techniques. Specifically, the terrestrial coupling index uses the daily slope of the soil moisture-surface flux relationship as weighted by the standard deviation in soil moisture to determine the degree to which soil moisture changes drive surface flux variability. But does not require multiple carefully constructed simulations (See Figure 1 from Dirmeyer 2011. And Figure 1 from Part 2. Needs s...
