Data delivery
use of EIONET CDR
do not duplicate delivery via ... confusing and time consuming to check the duplications ... EU MS need to notify the Commission by that the data has been delivered to the CDR
follow the instruction of EIONET helpdesk - use folder “European Union (EU), obligations“ for data delivery

Data files
use correct XLS files even if no excedance was observed ... do not send only or upload text file (letter) ... do not use MS Word, HTML formats

1h exc. reporting (1)
do not use one monthly file for delivery exceedances info from more months, use separate updated file: ... IT04401.xls ... April file from Italy ... IT04402.xls ... updated April file
do not forget to report exceedance of information threshold in case of reported alert threshold exceedance

1h exc. reporting (2)
do not forget to report information in case of no exceedance occurrence: ... xls file with a text message “there were no exceedances in COUNTRY in MONTH YEAR”
do not write any information in tables Alert and Information in case no exceedances – write it in table on Comment sheet

8h exc. reporting
report only one 8h value per day, i.e. maximum 8h value, not all values exceeded 120 µg/m3

Data completeness in 2004
several stations missing in stations list, but 8h, 1h exceedances and 1h maximum data were delivered
no 1h monthly maximums delivered for stations mentioned in station list

Station’s info (1)
do not repeat list of stations every month ... report only information on new station(s) on Station sheet, information about closing station on sheet Comment and preferably the complete list of stations operational during summer season April – September on sheet Station in summer summary file (most of countries did it last summer)

13. EUROPEAN TOPIC CENTRE ON AIR AND CLIMATE CHANGE
Station’s info (2)
use only recommended format for geographical co-ordinates: do not use format 19°36´32´´ or degrees, minutes and seconds in separate columns
use correct abbreviations for Type of ozone station as defined in Directive 2002/3/EC, Annex IV U ... urban S ... suburban R ... rural RB ... rural background
EUROPEAN TOPIC CENTRE ON AIR AND CLIMATE CHANGE

14. EUROPEAN TOPIC CENTRE ON AIR AND CLIMATE CHANGE
Station’s info (3)
do not use national characters (alphabet) in station’s names
use the same identification for the same station every month: do not deviate names of stations, codes etc. ... if it is needed due to reorganization of networks, please, update all previously transmitted monthly files
use EU code for station identification

Last remark on data
All values are to be expressed in µg/m³. The volume must be standardised at the following conditions of temperature and pressure: 293 K and 101,3 kPa
The time is to be specified in Central European Time.

Summary (1)
to correct all - although small - mistakes in delivered files before/during data processing is very time consuming
main problem every summer is lack of clarity or missing data in the meta-information of stations: it is huge work to link exceedances information with station meta data (using all available sources, i.e. last year(s) ozone and EoI data reported)
EUROPEAN TOPIC CENTRE ON AIR AND CLIMATE CHANGE

17. EUROPEAN TOPIC CENTRE ON AIR AND CLIMATE CHANGE
Summary (2)
use strictly rules described in manual “Directive 2002/3/EC relating to ozone in ambient air, Procedures and Formats for the exchange of monthly and summer reports”
