I suggest package PowerSDI (https://cloud.r-project.org/web/packages/PowerSDI/index.html) be added to the Hydrology CTV.

The PowerSDI calculates two Standardised Drought Indices (SPI and SPEI) using NASA POWER Data.
The package also verifies if the indices' estimates meet the assumption of normality and how well NASA POWER estimates represent real-world data. Indices are calculated in a routine mode. Potential evapotranspiration amounts and the difference between rainfall and potential evapotranspiration are also calculated. It adopts a basic time scale that splits each month into four periods where 'TS=4' corresponds to a 1-month length moving window (calculated 4 times per month) and 'TS=48' corresponds to a 12-month length moving window (calculated 4 times per month).

Yeah that sounds great. Would you be willing to add them via a PR? Here is an example: #148

No problem. I just did it myself :)
