OCTOBER 2019
GLOBAL AVERAGE
( LAND + OCEANS )
October’s bulk-layer
atmospheric temperature
anomaly of +0.46°C
( +0.83°F )
represented the second
warmest October reading
of the past 41 Octobers
in our satellite record,
though statistically tied
with two other years.
OCTOBER -- GLOBAL
( LAND ONLY )
A tie with 2017
for the warmest October
land only in the record
( +0.74°C, 1.33°F ).
OCTOBER -- US
48 STATES ONLY
The conterminous U.S.
had an average October
( -0.03°C, -0.05 °F )
with north central and
northwestern portions
well below average.
OCTOBER -- US
ALASKA ONLY
The warmth in Alaska
lifted the 49 other states’
average to
+0.25°C ( +0.45°F ).
METHODOLOGY:
As part of an ongoing joint project between UAH, NOAA and NASA, Christy and Dr. Roy Spencer, an ESSC principal scientist, use data gathered by advanced microwave sounding units on NOAA, NASA and European satellites to produce temperature readings for almost all regions of the Earth.
This includes remote desert, ocean and rain forest areas where reliable climate data are not otherwise available.
Research Associate Rob Junod assists in the preparation of these reports.
The satellite-based instruments measure the temperature of the atmosphere from the surface up to an altitude of about eight kilometers above sea level.
Once the monthly temperature data are collected and processed, they are placed in a “public” computer file for immediate access by atmospheric scientists in the U.S. and abroad.
The complete version 6 lower troposphere dataset is available here:
Archived color maps of local temperature anomalies are available on-line at:
Neither Christy nor Spencer receives any research support or funding from oil, coal or industrial companies or organizations, or from any private or special interest groups.
All of their climate research funding comes from federal and state grants or contracts.
