Anyone know who provides the BBC Weather pages with their air
pollution forecasts ?

The BBC London weather page at

http://www.bbc.co.uk/weather/2643743

shows "pollution LOW"

whereas the more authoritative page at

http://www.airtext.info/

shows

Forecast of Air Pollution Index for:
Saturday February 11th, 2012
Central London:
MODERATE air pollution expected everywhere

Indeed, it looks as if the level appears to be 6 at the high end of
the moderate band.

The BBC site may be less "authoritative", but given the latest
measurements is appears more accurate!

Since the BBC weather information is provided by the Met Office, it
ought to be authoritative.

Thanks for that link.

Checking now has given the results for the London automatic monitors

ozone 9 reading low (8x1,1x2)
hourly mean NO2 11 reading low ( 9x2,1x1,1x3)
max 15min so2 6 reading low (6x1)
24hr mean pm2.5 1 reading low ; 8 reading moderate (1x3, 3x4,4x5,1x6)
24hr mean pm10 1 reading low ; 6 reading moderate (1x3,4x4,1x5,1x6)

Given the major health concerns associated with particulates, I think
the alert level of the BBC forecast (wherever it is derived from)
should have been higher , in line with the airtext warnings.

With the wind having been fromthe east in southern England, you would
certainly think that a fair amount of pollution might have been brought
over from the Continent.

As usual, the BBC page is showing LOW for the forecast today.

The Defra London monitors page, reflecting past performance shows low
for ozone,sulphur dioxide and NO2, BUT

for PM 2.5 particles , 1 moderate (6) and 7 high (2x7,4x8,1x9)
for PM 10 particles 3 moderate (1x5,2x6) and 4 high (3x7,1x9)
