Status: CLOSED. some feedback was received from DWD and as part of the software review of the latest release.

Action DA/NWP-21 on Thomas August and Fiona Smith: Determine whether the IASI-NG End Users Requirements Document can be shared. If any questions remain, discuss at ISSWG how to help NOAA formulate a requirement on maximum inter-detector calibration differences.

Status: CLOSED: The relevant clause in the IASI-NG EURD is identical to that of the IASI EURD. This was shared with Mitch Goldberg, Chris Barnet (who we believe instigated the action) Dave Tobin and Sid Boukabara. There has been some further discussion.

Action DA/NWP-22 on Karen St. Germain: Send to WG co-chairs the target performance and reference architecture for the Broad Area Announcement to industry for next-gen instrument proposals, including identified areas for potential trade-offs.

Status: CANCELLED. Karen moved jobs before this was complete. Co-chairs contacted Vanessa Griffin and Mitch Goldberg who were not aware of the documents Karen had intended to send. Feedback to NOAAs proposals for next-gen satellites is coordinated through SAT, chaired by Sid Boukabara, although this is not fully international. More info to be delivered at this conference.

Action DA/NWP-23 on Working Group Chairs: Send out an email to the DA/NWP WG members containing supporting documentation from Karen St Germain inviting participation in a working group to make recommendations to NOAA on the proposals for next-generation satellites.

Action DA/NWP-24 on NWP Working Group Members: Respond to the request from Karen St Germain and DA/NWP WG co-chairs to join a working group to provide feedback to NOAA on proposals for next-generation satellites

Status: CANCELLED. See above

The following recommendations were made at the last meeting, some of which are long-standing.

Recommendation DA/NWP-1 to all relevant space agencies: The constellation of at least three orbits (early morning, morning, and afternoon), each with full sounding capabilities (IR and MW), should be maintained. The overpass times of operational satellites with sounding capability (IR and MW) should be coordinated between agencies to maximize coverage and include a satellite in early morning orbit.

Recommendation DA/NWP-2 to the Satellite Agencies: In support of maintaining a robust global satellite observing system, instrumentation to allow continued sounding of the temperature of the upper stratosphere and mesosphere (as for the SSMIS UAS channels) should be explored.

Recommendation DA/NWP-3 to the NWP Centres: : Work to assess the impact of the upper atmospheric sounding channels of SSMIS in NWP and determine the information content unique to those channels e.g. via data denial experiments.

Recommendation DA/NWP-4 to Space Agencies: New operational data dissemination infrastructure should be tested at an early stage (well before launch) with simulated data.

Recommendation DA/NWP-5 to Space Agencies: There should be open and early access to new satellite data for all NWP centres to help with calibration and validation.

Recommendation DA/NWP-6 space agencies: Satellite agencies should work with their primary user communities to assess the limitations in the exploitation of satellite data, and also engage with users less closely connected to their agencies

Recommendation DA/NWP-7 to funding bodies of NWP centres and space agencies: Consider, as part of the cost of satellite programmes, providing computational and personnel resources targeted at operational NWP centres to optimise the public’s return on investment from these expensive measurement systems.

Recommendation DA/NWP-8 to Data Providers: Agree standardized procedure for calculation of NEdT estimates for inclusion within BUFR for microwave data.

Recommendation DA/NWP-9 to Data providers: Include azimuthal viewing and solar angles as appropriate in BUFR for present and future instruments.

Recommendation DA/NWP-10 to Space Agencies and data providers: When designing new or modified BUFR formats, please circulate drafts to the NWP community via the NWP Working Group for feedback, prior to submission to WMO.

Recommendation 11 to EUMETSAT: Communicate when NSR for S-NPP CrIS will be switched off and provide a parallel stream for a short time (a few weeks) to allow users to transition to the new dataset.

Recommendation DA/NWP-12 to Data Providers: When using PC compression, noise normalisation should be performed using the full noise covariance matrix.

Recommendation DA/NWP-13 to EUMETSAT: Proceed with work on the use of Hybrid PC compression and investigate practical application of this method, including the incorporation of granule-based vectors in BUFR.

Recommendation DA/NWP-14 to NWP Centres: All centres should use the IASI Hybrid PC-compressed dataset to ensure they are prepared for MTG-IRS. Users are requested to provide feedback to EUMETSAT on the use of these data.

Recommendation DA/NWP-15 to Data Providers: If a change to data processing results in a change in brightness temperature of 0.1K or 20% of NEdT (whichever is smaller), this should be made clear in notifications to users. These notifications should be made no later than 8 weeks before the change and test data should be provided if possible.

Recommendation DA/NWP-16 to Data Providers: The overlap period where one satellite resource is replacing another should be chosen after consultation with the user community and should follow WMO guidelines.

Recommendation DA/NWP-17 to DBNet providers: Switch on the production of VIIRS cluster information for DBNet for IASI and CrIS.

Recommendation DA/NWP-18 to NWP Centres: Evaluate IKFS-2 data.

Recommendation DA/NWP-19 to Data Providers: In order to facilitate evaluation of new data by NWP centres, aim for distribution in near-real time.

Recommendation DA/NWP-20 to NWP centres: Produce impact studies for DBNet and low latency data and present results at the Seventh WMO Workshop on the Impact of Various Observing Systems on NWP in Seoul in May 2020.

Recommendation DA/NWP-21 to NWP-SAF: Share ECMWF instrument event records with the community, together with illustrative monitoring plots where appropriate.

Recommendation DA/NWP-22 to NASA and NESDIS: Continue to provide AIRS Aqua data in real-time to NWP centres for as long as calibration of the instrument is possible.
