# Thermometers in Angola? Claims of NOAA fraud, etc

This one is going around denierville now, as reported by CD:

Now, I'm not well-versed in the specifics of the GHCNM data set, but I can't actually find the land-only map on NOAA's site. Is this using provisional data before it's been fully collected? My initial thought is that there are thermometers, but not enough historical data to calculate departure from average using the same baseline. Anybody knowledgeable in GHCNM know what the process is for filling in the gray areas?

I'm getting somewhere, I managed to find the NOAA stations in Angola. So the claim that "NOAA has no thermometers in Angola" is disproven by the existence of these weather stations in Angola!

I'm still not sure why the data from those stations aren't reflected in the map though.

• It is true that NOAA has no thermometers there. The data comes from the national weather service.

More seriously, naturally there are stations in Angola.  Whether you see a value in the plot depends on how much data was already available, whether the newest data was already processed and every plot has its own criterion for how much data needs to be available before you show an average.

The date on the plot is on the day NOAA and GISS give official values for the last month. So one could be before and one after then last big update.

Plus the article is written by Tony Heller aka Steve Goddard. There is a non-zero probability they are fake. That guy is too toxic for WUWT, interesting he is not for Climate Depot, scientist harassment headquarter.

P.S. I love the advertisements on Climate Depot. Shows you what kind of audience they have: old man who you can sell and unproven medical nonsense.

• Tony is a loon .
That is probability a screen shot of the data before all stations were in.

The site for the world network is here
Global Observing Systems Information Center (GOSIC)
http://www.wmo.int/pages/prog/gcos/index.php?name=ObservingSystemsandData#surface

An interactive map of world stations is here .

The interface is a little clunky as I have never used it before I can not help you to learn how to navigate it but the stations and data is there if you make the effort .

I found the chart in question, on NOAA's site:

https://www.ncdc.noaa.gov/temp-and-precip/ghcn-gridded-products/

Is is that still up to date? Or does version 3.3 not include all stations yet?

Or is that just a representative picture of what the data looks like (made prior to getting the complete data), rather than a final snapshot of the August data?
• At least that version from the 16th of September should have all the data that the other NOAA graph showed on the 12th. Thus that there is difference in missing data is then likely because the graphs have other requirements for the number of stations in a grid box. GHCN gridded uses the anomaly method, which requires reasonably complete data over the period 1981-2010. It could be that the other graph looking at extremes is computed with a smarter method (like BEST does).

All stations are most likely not included yet. Part of the data is shared in near real time for meteorology. Those daily values are used to compute the first numbers. This kind of data often still got measurement problems in them. Thus after the end of the month again monthly summaries that have been quality controlled are send around. If they are from the same stations, they replace the lower quality near real time data.

And there are many more climate stations that are not online at all or for which the national weather service does not share the data automatically. It can a long time and many emails to get such updates. The online ones are typically professional stations, while the data from voluntary observers takes a bit longer. In the past they would send post cards to the weather services and the service would have to type in the data. Maybe for some stations in poorer countries it still works that way.
• There were four stations in Angola on the Google Earth overlay from the link on this page:
http://www.wmo.int/pages/prog/gcos/index.php?name=ObservingSystemsandData#surface

They are well-spaced over the country.

GISS has stations in the vicinity with dates of operation (it uses NOAA's GHCN). Mongu is just over the border in Zambia and has a long continuous record.

Mavinga is in Angola, but doesn't have much of a history and isn't current. Menongue is similar.

Angola has been war torn over the years. I'd be surprised if there was any continuous record at any weather station.

As for the chart - silly stuff. The world map is worked out using extrapolations from data on land and sea. It's been hit hard by drought recently. You people probably know more about that sort of thing than I do. (Nick Stokes might have some info.)
