Topic:  Termination of Legacy GHE

Date/Time Issued:  March 3, 2025 2131Z
 
Product(s) or Data Impacted: Legacy Global Hydroestimator (GHE)
 
Date/Time of Initial Impact: March 4, 2025 1600Z
 
Date/Time of Expected End:  Permanent
 
Length of Event: Permanent
 
Details/Specifics of Change:
The legacy on-premises version of the Global Hydroestimator (GHE) is being retired. It
is being replaced by the global Enterprise Rain Rate algorithm, which has been running
in the NCCF Cloud environment since Nov. 7, 2024.
PDA distribution of legacy GHE products will stop on March 4, 2025, at 1600Z.
Due to requirements of other legacy products, notably ETRAP, the product itself will
continue, with ADDE /McIDAS distribution, until approximately June.
Please ensure all subscriptions are set to receive the NCCF-based Enterprise Rain
Rate algorithm as detailed in the table below.
This change will not be performed during Critical Weather. The termination will be
postponed to 1600Z on the next, non-Critical Weather Day.
