09:30 Start NF forum - Véronique Riffaut IMT nord

• NF technical and scientific forum –> 274 registered 26 countries

  • recommendations to RI Comittee
  • inclusive
  • open to whole ACTRIS community
  • scientifi expertise and technology developments
  • elec NF representatives in the interim RI Comittee
  • convene physically or virtual once per year
  • Central facility should participate to the meeting
  • will evolve with new ACTRIS ERIC

• NF forum

09:40 Result of NF Forum survey

• large amount of people from different area of ATRIS
• Peak in Instrument maintenance for engineer and technical staff
• big peak in measurement interpretation and scientfic analysis for phd senoir and junior researchers
• Iwona is reprenting Aerosol remote sensing, lucas is for cloud remote sensing

**09:50 Actris components for aerosol remote sensing - Iwona (represented by Doinae)

• 4 dimensional observations of characteristic aerosol properties
  –> Air quality, dynamic, climate variables, CAL-Val stellite (Aeolus, Sentinel, Earthcare)

• Requirements for Lidar

  • high power lidar + sunphotometer max 1km horizontal distance
  • Minimum lidar = 1 elastic+1 raman+1 polar at same wavelength
  • Full overlap 300m in max 5 yrs after initial acceptance
  • min vertical alt=10km (raw 1064)
  • min height res=15m
  • max time res=60s
  • Additional features: eyepiece+camera+polar calibrator+pretrigger
  • photometer=Cimel318T

• Variables

  • long list
  • we need complicated aerosol lidar and multivalenghts to reach all list of variables
  • Show exemple of measurements
  • Then we can reach microphysical properties of Aerosols

• Scientific otputs: many projects

  • Atmo-Access: thematic TNA, pilot TNA for cal/Val
  • RI-Urbans: products and methods, measurements quality framwork
  • Key ublications

** Aerosol-in-situ component - Kostas Eleftheriadis**

• Map of NF facilities: more than 100 NFs
• what do we do: best state of the art, provide high quality data

10:10 Cloud remote sensing - Lucas Arboledas

• clouds major cmponents in Earth radiation budget
• vary rapidly in time and space
• to obtain quantitative information of spatial-temporal evolution
• within Actris: btain vertical clouds structure
• variable & instrumentation
  • continuous long-term vertical profiles cloud fraction and water-ice cloud properties
  • 3 core instruments: doppler cloud radar, aerosol lidar, microwave scanning radiometer, doppler wind lidar
  • minimum required: cloud radar, ceilometer, dual-freq micrwave radiometer
  • variables…

10:20 Cloud in situ - Anti Hyvärinen FMI Finland

• handful of mountain stations
• Ground truth
• Lack of long record of standardization

10:30 Reactive trace gases remote sensing - Markus Leuenberger (presented by Bart Dils)

• scope: FTIR, UVVIS, Lidar) sample partial atmospheric columns
• suited for sat validation
• tie observation to emission
• expand the range of species that can be retrieved
• List of variables

10:40 Reactive trace gas in situ- Christine Braban

• NOx, VOCs, condensable vapours

10:50

11:00 Group picture

11:30 Common issue and respond to needs

• Data submission to the centre (responses of the srvey)
  • fairly difficult said the users
  • instrument dependent also said the user
• dysfunctions to be discussed
  • data submission to SC
  • robust and flexible raw lidar data converter tool+2D/3D visualization

**11:45 Feedback and questions on labelling process, pilot labelling, interface, schedule

• clarification?

• TC will needs to evaluate the pilt station for labelling and they have a limited ressources so we cannot open labelling to lots of stations

• step 1: The country proposes the NF to be included in ACTRIS (done already). check where is SIRTA

• step 2 HO gives the facility to the labelling interface

• step 3: the NF provides necessary information on existing and planned facility and instrumentation (general form and technical form)

• then see steps 4 to 9. 9: Actris director general grant initial label

• Presentation of the template of commitment letter. P. Laj is questionning the strong commitment about the 5 years engagment of doing long term data providing by NF regarding the available ressources that will need to be involved for that. Request modification of the terms of the commitments.

• Question from a german: why NF should go through this commitment since the country already did it by proposing the facility? R: question of fundings. Country commits only supportingthe facilities but then facilities needs to commit haow they are going to arrange for the 5 yesr engagment.
