Regarding the Aridity Anomaly Outlook Index, consider the following statements:
I. It is published by NITI Aayog.
II. It measures the pH level of the soil.
III. Its parameters include actual evapotranspiration and calculated potential evapotranspiration. Which of the statements given above is/are correct?

Aridity Anomaly Outlook Index An anomaly from the normal value signifies a water shortage in these districts that could directly impact agricultural activity. It is Developed by the India Meteorological Department (IMD) and not by NITI Ayog. Its parameter includes, Actual evapotranspiration and calculated potential evapotranspiration, which require temperature, wind and solar radiation values. Actual evapotranspiration is the quantity of water that is actually removed from a surface due to the processes of evaporation and transpiration. Potential evapotranspiration is the maximum attainable or achievable evapotranspiration for a given crop due to evaporation and transpiration.
