Climate Monitoring Resources

I’ve gathered together a list of regularly updated resources for climate monitoring. This is the kind of information you can use to get a reasonably up-to-date view of what’s happening around the world in the climate. This can be surprisingly hard to do and there are some blind spots, which are slowly getting filled over time. Thanks to Ruth Mottram, Andrew Watkins, Oliver Bothe, Mark McCarthy, Tim Osborn, Robert Dunn for suggestions and (many) additional links.


The eye of Sauron (The BAMS State of the Climate Report)
Once a year its burning gaze sweeps the earth frazzling hapless Orcs that get in its way.
A lesser eyelet of Sauron would be the WMO annual statements:

One ring to rule them all
NCDC State of the Climate report is the uber monthly resource. Not only do they provide a global perspective, but they also link to primary sources wherever possible

(a second ring to sort out the bureaucracy and such)
JMA also do a similar kind of thing to NCDC, but its more data oriented, sifting CLIMAT and SYNOP reports and highlighting interesting events in a more automated way.
Particularly nice is the CLIMAT viewer which gives access to CLIMAT info in a map and click form

(a third ring etc.)
WMO has a list of national met services. Climate isn’t necessarily managed by the met service. Some countries have an Agromet service or some sort of Hydrological service. These can be good starting points, but they can also mire you down in endless click circles and dodgy google tranlsations

(A fourth ring running around in the background making sure all the computers work)
Climate Diagnostic Bulletins from CPC. This is a more technical exploration of the climate, focusing on large scale flow and such like:

(A fifth.. no, this is silly)
IRI map room. Uses CMAP data sets to provide up to date climate monitoring

Country or Regional resources:

This is something of a mixed bag. Some countries provide nice monthly summaries. Some provide news items about unusual events. Some do both, in different places. These are the ones I’ve found that have some form of regular or semi-regular climate reporting.

WMO Country Profile Database
The WMO provides some country level climatological information.

Africa – WMO Region 1
Regional Climate Centre fro WMO Region 1: Tunisia (covers North Africa)
ACMAD home –
ACMAD climate bulletins (with archive)
CPC African Desk
Tanzania State of the Climate

Asia – WMO Region 2
Regional Climate Centre for WMO Region 2: China
Regional Climate Centre for WMO Region 2: Tokyo (there’s one for Moscow too, but all the climate monitoring information is more than a year in arrears)
India – monsoon information (note this is a new page and it doesn’t work for me)
South Korea – climate summaries – DISCONTINUED
Russia – monthly and other summaries (in Russian, unsurprisingly)

South America – WMO Region 3
Argentina – facebook page with up-to-date info and main website for special statements
Mexico – monthly temperature and precip summaries with ENSO impacts etc.
Brazil (some interactive map plotting tools)
Chile: Boletín Sequía Meteorológica
Venezuela (a few months in arrears):

North America – WMO Region 4

Southwest Pacific – WMO Region 5
Australian Bureau of Meteorology General front page Special reports etc. Video overviews of the recent climate with an outlook for the next while Older outlooks

coral bleaching on the Great Barrier Reef:
Indonesia – google translate doesn’t like some of these pages. Not sure why, but it can translate the text if you copy-paste it. Alternatively, learn the language.
New Zealand climate update
Fiji – monthly weather summaries

Click to access Summary1.pdf

Tonga – monthly weather summaries (only past month, no archive, wayback archives very sporadic)

Click to access last_months_climate_summary.pdf

Europe – WMO Region 6
DWD Region VI monitoring page
Climate Indicator Bulletins (not very regular, but very useful when they appear):
Europe Severe Weather Database:
ECA&D map plotter
UK Met Office

Ilmastokatsaus-digilehti kesäkuu 2020

Iceland – they have some data for selected stations
Meteo France weather and climate news;jsessionid=1C42B3A76EB619CD0355F9DC38B507DC.11

Slovakian climate blog
Slovenia natural hazards news
Serbia, pdf monthly bulletins that google translate mangles
KNMI – knowledge centre – provides in depth studies of certain events.
Met Eireann – The Irish Met Service Online – Monthly weather summaries
Switzerland – English versions can lag German versions
Denmark – annual temperature plots
Portugal – lots of plots, with info under climate and agromet tabs

Wikipedia is pretty good on tropical storms

Snow and ice
The PolarPortal is a good source for tracking Arctic ice and climate, such as sea ice extent and thickness as well as Greenland ice sheet surface conditions:
National Snow and Ice Data Center (NSIDC) sea ice
Greenland ice sheet
Rutgers snow lab for northern hemisphere snow cover monitoring
Swiss Glacier Monitoring Service (GLAMOS)
US Great Lake ice cover

Odds and Ends

KNMI Climate Explorer – a handy but limited tool for playing with lots of data sets
Weather Underground: monthly summaries of climate events and extremes and an awkward and slow but handy tool for finding heatwaves by station
Reading Weather and Climate blog
Ogimet – amateur store of CLIMAT/SYNOP messages
The Euporias weekly digest
Extreme temperatures around the world
EUMETSAT Case Studies

For some events, you can find information on impacts here:
Reading Global Hazards Weekly Bulletin

Slower update cycles
The US Global Change website has maps an info, that’s apparently updated, but I’m not sure how frequently.
IPCC AR5 WG1 has a kind of monitoring component, chiefly Chapters 2 and 3.
The Deep-C project has more resources on the Pause/Hiatus/Hiccough/Speedbump/Slowdown in warming
CSIRO produce state of the climate reports too

  1. Thanks for doing this John, these kinds of things are very useful.
    This if for empirical data only, no models or reanalyses?

    • Thanks Jim, I’m glad you find it useful. It’s for any kind of climate monitoring resource provided it’s updated regularly and that I think might be useful.

    Hi John, thanks, this is amazing. I wish I had seen it earlier in my career. I’d know stuff

  3. can be useful — get notice when there’s a minor or major change on a website. Hat tip to James Annan at Stoat for mentioning that tool.

  4. I previously used the data from Marine Copernicus, Hycom, and Remote Sensing Systems. Each provides varied data from the layers of ocean vertical bottom to the wind satellite observation.
    Hope it’s useful 🙂
