1 Way Forward in Using Radar Data for Climate Monitoring Elena Saltikoff, 30 March 2017

2 OPERA in Europe project club (since 1999) datahub (since 2012) 30 members 200 radars mean distance 120 km Exchanging knowledge and data from operational Weather Eadars in Europe 03/04/2017 2

3 Storm 12 Jan (when satellite cleaning was off)

4 1-year accumulation

5 1-year accumulation 2012 Do you really want to use data like this? Many networks have been upgraded in

6 TheWayForward A. Assess the present situation a. Ensure all key players are involved b. Collect updated requirements of the climate monitoring c. Assess existing international archives, their extent and quality d. Assess existing national archives, their extent and quality B. Suggest procedures for old data a. Suggest national level efforts b. Suggest international efforts C. Define recommendations for future activities a. Data acquisition b. Quality assessment c. Archiving d. Metadata

7 A. Assess the present situation a. Ensure all key players are involved: a. Policy limits: Universities? Non-NMS radar owners? b. Iterate a list among stakeholders (OPERA, IPET-OWR, the usuals) c. How do we get a list of climate players? b. Collect updated requirements of the climate monitoring a. This group or a wider list? c. Assess existing international archives, their extent and quality a. Ask the key list b. Iterate the list among stakeholders (OPERA, IPET-OWR) d. Assess existing national archives, their extent and quality a. Survey?

8 Get the radar people and climate people to talk to each other

9 What are we talking about when we talk about radar data Is radar just a bad gauge? The Atmosphere is 3D

10 Specialcharacteristicsof radar data There is a lot of it. Measured quantities are not the used quantities; development ongoing Power (Watts) and phase (deg) Power (Watts) and phase (deg) dbz, VRAD, KdP, ZDR, Auxiliary data mm/h, m/s, hail,

11 Changesof paradigm 1 Power (Watts) and phase (deg) Power (Watts) and phase (deg) dbz, VRAD, KdP, ZDR, Definition of the radar parameter From dbz to mm or to I&Q? Or dbzh, DBZc Auxiliary data mm(kdp) mm/h, m/s, hail,

12 Changesof paradigm 2 Definition of a radar observation : Volume? Sweep? (Era of images long past)

13 B+C: Chickenor eggfirst? Suggest procedures for old data ( ) National International IPR issues? Come back to this question Define recommendations for future activities Data acquisition Quality assessment Archiving Metadata IPR issues
