Subject: Discontinuation of stratospheric temperature and height
products derived from the NESDIS retrieval soundings of the Advanced
Microwave Sounding Unit (AMSU) on board the NOAA Polar Orbiting
Environmental Satellites (POES) on June 15, 2025.

The National Centers for Environmental Prediction (NCEP) Climate
Prediction Center (CPC) will discontinue stratospheric temperature
and height products derived from the NESDIS retrieval soundings of
the Advanced Microwave Sounding Unit (AMSU) on board the NOAA Polar
Orbiting Environmental Satellites (POES) on June 15, 2025. These
changes are the result of the discontinuation of data gathering for
the POES NOAA-15, -18, -19 on June 16, 2025 at 1800 UTC
(https://www.ospo.noaa.gov/data/messages/2025/04/MSG_20250425_1900.
html).

As a result the following products will be discontinued:

(A) The CPC/AMSU Stratospheric Temperature and Height Analyses
including:
CPC/AMSU 12Z Analyses
(https://www.cpc.ncep.noaa.gov/products/stratosphere/strat_a_f/#cpc
t12z)
CPC/AMSU NOAA-15 Temperatures
(https://www.cpc.ncep.noaa.gov/products/stratosphere/strat_a_f/#cpc
t15)
CPC/AMSU NOAA-15 Heights
(https://www.cpc.ncep.noaa.gov/products/stratosphere/strat_a_f/#cpc
z15)
CPC/AMSU NOAA-18 Temperatures
(https://www.cpc.ncep.noaa.gov/products/stratosphere/strat_a_f/#cpc
t18)
CPC/AMSU NOAA-18 Heights
(https://www.cpc.ncep.noaa.gov/products/stratosphere/strat_a_f/#cpc
z18)
CPC/AMSU NOAA-19 Temperatures
(https://www.cpc.ncep.noaa.gov/products/stratosphere/strat_a_f/#cpc
t19)
CPC/AMSU NOAA-19 Heights
(https://www.cpc.ncep.noaa.gov/products/stratosphere/strat_a_f/#cpc
z19)

(B)The CPC Global Temperature Time Series analyses. These graphics
are located at:
https://www.cpc.ncep.noaa.gov/products/stratosphere/temperature/.

(C) The CPC Stratosphere Troposphere Monitoring products which
include zonal mean time series of temperature, zonal wind,
geopotential height and the amplitude of the height field s wave 1,
wave 2, and wave 3.

Viable alternatives:

(A) The GFS analyses and forecast products are a comparable
alternative to the CPC/AMSU Stratospheric Temperature and Height
Analyses and are available at:
https://www.cpc.ncep.noaa.gov/products/stratosphere/strat_a_f/#emct

(B) The GFS and GEFS time series analyses and forecast products are
a comparable alternative to the CPC Global Temperature Time Series
analyses and are available at:
https://www.cpc.ncep.noaa.gov/products/stratosphere/SSW/

The changes listed above may impact users that currently utilize
graphics from these products and thus code adjustments may be
necessary.
