Harry Harmens and Gina Mills
(ICP Vegetation, CEH Bangor, UK)
* Supported by Defra (UK), NERC (UK) & UNECE
30th ICP M&M TFM, 7-10 April 2014, Rome
27th ICP Vegetation TFM, Paris
 28 – 30 January 2014, Paris. Hosted by the French Environment
and Energy Management Agency (ADEME), in collaboration with
AgroParisTech, INRA, Muséum national d’Histoire naturelle
(MNHN) and Université Paris-Est Creteil (UPEC)
 84 experts from 22 countries attended the meeting
 28 January: one-day ozone critical levels workshop to review
current status and make recommendations for amendments to
Chapter 3 of the Modelling and Mapping Manual: ‘Mapping critical
levels for vegetation’. Discussion continued during TFM.
30th ICP M&M TFM, 7-10 April 2014, Rome
Revisions main text Chapter 3 (1)
 No changes to the existing critical levels
 New references included where ozone response functions
and supporting evidence for ozone critical levels have been
published
 Text related to integrated assessment modelling (Section
3.5.2.6) updated:
o New terminology for the simplified generic ozone flux –
PODYIAM will replace PODYgen (PODY = Phytotoxic Ozone
Dose above a flux threshold of Y nmol m-2 s-1)
30th ICP M&M TFM, 7-10 April 2014, Rome
Revisions main text Chapter 3 (2)
 New POD3IAM – effect
relationship for use in
integrated assessment
modelling at European scale
only (for effects of ozone on
wheat, 90 d exposure period)
 Critical level: 8 mmol m-2
(representing 5% yield decline)
 For use in scenario analysis and optimisation runs within GAINS
to provide indication of potential effects on wheat yield under
non-limiting water availability
 Two parameterisations flux model: 1) Northern & Central Europe,
2) Mediterrannean areas (as defined in the M&M Manual)
Revisions Annexes Chapter 3
Crops:
 Parameterisations flux model for grapevine,
maize, soybean and sunflower
 Revised Mediterranean flux parameterisation
for wheat (bread and durum wheat)
 References to additional published flux models for
local-scale application in the Mediterranean region for
bean, barley and tomato
Trees:
 Parameterisation ozone flux model for poplar
(Semi-)natural vegetation:
 Reference to additional published flux model for
local-scale application for Cocksfoot (Dactylis glomerata)

Photosynthesis – preliminary results
CROPS
 Net photosynthetic rate:
- Significant decline with increase in daylight ozone (cereals)
 Asat (light-saturated rate of net photosynthesis):
- Significant decline with increase in daylight ozone
- Non-cereals more affected than cereals
 Vcmax (maximum rate of Rubisco carboxylase activity):
- Significant decline with increase in daylight ozone
OTHER VEGETATION
 No significant effects of ozone on photosynthesis (wide
confidence intervals due to lack of data; only 3 papers)
