ClimaParams.jl Release Notes
========================

v0.10.15
------
- Adds 2 timescale parameters for relaxing forced single column model temperature, humidity, and wind velocity towards the forcing profile ([#209](https://github.com/CliMA/ClimaParams.jl/pull/209))
- Adds 2 parameters that describe the height at which the single column model profiles should be relaxed at ([#209](https://github.com/CliMA/ClimaParams.jl/pull/209))

v0.10.14
------
- Remove all dependencies ([#208](https://github.com/CliMA/ClimaParams.jl/pull/208))
