GATNDOR quarterly telecon (Jan 2014)

Date: Tuesday, 11. February 2014

Time: 17:30, Europe Time (Berlin, GMT+01:00)

Meeting Number:

Meeting Password: GRUAN

Present on the call: Fabio Madonna (FM), Dian Seidel (DS), Greg Bodeker (GB), John Dykema (JD), Tom Gardiner (TG), Dave Whiteman (DW), Hannes Vogelmann (HV)

Apologies in advance: Peter Thorne, Kerstin Ebell, Alessandro Fassò


1. Update from the topics.

1.1 Status of the paper “Statistical modelling of collocation uncertainty in atmospheric  thermodynamic profiles” by Fassò et al.

FM: Fabio summarized the status of the above mentioned paper. The reviewers asked to mainly improve the language, to make the bridge between atmospheric science and statistical communities. The discussion phase on AMT journal closed at the end of December.

HV: Alessandro, is their already a date, when your paper will be published in its final version? I’m almost ready with my variability paper which also adresses the collocation topic and I would like to cite your work.

FM:  The Editor’s final opinion should come soon.

1.2 Status of the paper “Quantifying the value of redundant measurements at GRUAN sites” by Madonna et al.

FM: the manuscript is in an advanced status, already circulated among the co-authors (including mentors of ARM instruments). Needs a final revision and some refinements for Payerne data discussed in the manuscript. The manuscript includes data from five GRUAN stations.

Hope two submit it to Atmospheric Measurement Techniques within two weeks.

Comments from everybody welcome within two weeks or so

1.3 SASBE activities

JD: A manuscript about water vapor and temperature measurements completed by March this year. The manuscript demonstrates the use of SASBE approach for satellite validation. Data for three ARM sites have been considered.

FM: I think the work by Kerstin Ebell could support the SASBE activities. I ask to involve her at better level in the SASBE study

2. GATNDOR in the near future

GATNDOR is still populated but the team is no more active on new topics.

The team was established on the spirit of volunteers. It seems to me that now this spirit got lost somewhere in the GRUAN community. Does it make sense to have still GATNDOR or to merge it with the work of Task Teams?

I think the idea behind GATNDOR is still winning (a team focused on specific science topics relevant for GRUAN) but the GRUAN community should be more interested in this team and the recruitment of volunteers should not be a problem.

Dian, June, Alessandro, and me worked as volunteers with the support from several others interested in GRUAN. it is time to check if something has to change in the “GATNDOR model”

Fabio, after four years, will leave as a chair as soon as things become clear (ICM6).

DS: Thanks to Fabio for your four years of dedication to GATNDOR.

FM: I also suggest also to think about the involvement of new GATNDOR members that already showed to have possible links with the running topics or to a possible extension of them, but they are not yet really involved.

FM. I would like here to collect comments in order to show at the ICM-6 the opinion of the Team in the current status of GATNDOR during my talk in Tuesday, 11 (ICM-6 10-15 March 2014).

DS: We should collect a list of contributions by GATNDOR (a set of references of published and submitted work) for presentation at ICM6.

DS: And it might be interesting to track when we first started on these projects, and how long they took to complete. This would provide perspective on what’s reasonable to expect.

Unlike other GRUAN work and activities, which happen almost “operationally”, research projects can easily be delayed or neglected if researchers are busy with other funded activities. This is typical for unfunded research plans, even if the projects are important and interesting. The problem facing GATNDOR is mainly that the research we have identified as important to GRUAN and interesting is generally not funded.  This is not really a sustainable situation and not a good model for a standing committee.  Perhaps WG-GRUAN can oversee research needs for GRUAN and work to rally scientists and obtain resources for priority GRUAN research, without the need for a standing GATNDOR activity, which is bound to have more ideas for projects than resources to carry them out. Still, the focus on peer-reviewed research to provide a scientific underpinning for GRUAN should be a high priority.

DS: One other idea: There is an emerging activity within WCRP/SPARC (World Climate Research Program/Stratosphere-Troposphere Processes and their Role in Climate) to study fine-scale atmospheric processes (e.g, gravity waves, turbulence, tropopause structures, boundary layer structures, etc) using very high vertical resolution radiosonde data. Since GRUAN soundings are very appropriate to this effort, there should be a good opportunity for synergistic research between SPARC and GRUAN. And since these are meant to be process studies, this would help GRUAN focus on process applications (as opposed to long-term monitoring, for example, which requires a long data record).

GB: GATNDOR could work in future according to the following model. The team will take care of sending co-chairs projects that are highly relevant for GRUAN purposes. The team should quantify the real efforts and costs related to the projects. GRUAN community (co-chairs and TTs) should look for the funding support.

3. HORIZON 2020 funding opportunities

FM: Under the leadership of Peter Thorne, Alessandro, Tom and me are working on the proposal MAP-OUT to submit in one of the Horizon2020 (the new research and development program of the EU) calls.

All the documents and the current discussion around the call can be found at the following Etherpad.

You can access and have a look.

NOAA will be also involved (Tony Reale), as a US partner (not funded directly but supported by a EU institution). The consortium has 19-20 partners.

Part of the current and proposed new GATNDOR topics might survive within this proposal if funded (collocation, atmospheric variability, and assessment of data usage as input for RTMs)

FM: the project will deal with the identification geographical mapping of existing gaps in the ground based observing capability for the monitoring of climate and for satellite cal/val. A scientific assessment and a prioritization of these gaps if foreseen. More details as the link provided above.

4. Conferences

Update of the participation at past or upcoming conferences relevant for GRUAN.

Climate Research and Earth Observations from Space – Darmstadt, Germany, 13-17 October 2014  (

5. AOB

6. Next activities to be defined after discussion at ICM6 in Washington.
