The IMERG monthly rain data for the upper reaches of the Ruaha River which proved to correlate well with the occurrence of zero flow at Mtera, stopped being produced in September 2021.
The IMERG rainfall data collection with version 7 started this July (2023). We are excited and looking forward to find out if the new data series will correlate as well as version 6, which will be tested from June – July next year (2024) onwards.
