Dear System Administrator / IDD Coordinator,
My name is Toni Biston, and I operate an independent research project
studying the latency, reliability, and propagation characteristics of
real-time meteorological observation networks.
A second part of the research examines whether earlier availability of
surface observations can provide measurable benefits for rapid-update and
short-horizon weather forecasting.
As part of this work, I am comparing push-based meteorological data
dissemination with publicly available HTTP/pull data services. I am
therefore looking for an LDM/IDD upstream willing to provide a small
real-time WMO surface-observation feed to a dedicated research node.
For the latency analysis, it is important to receive the original
operational observation products rather than derived, summarized, or
periodically aggregated datasets.
The research is primarily interested in:
original real-time surface observation reports;
both routine and special observations where available;
air temperature;
wind speed and direction;
wind gusts where reported;
observation timestamps;
original report/bulletin text;
WMO/LDM product identifiers and associated dissemination
metadata/timestamps where available.
Ideally, I am looking for access to IDS|DDPLUS, or an equivalent real-time
WMO text feed containing original surface-observation bulletins.
Only a relatively small subset of European observations is needed. If
fine-grained filtering at the upstream is inconvenient, receiving the
appropriate low-volume surface-observation product class and performing the
final filtering locally would be perfectly acceptable.
I do not require numerical model grids, radar, satellite imagery, or other
high-bandwidth products.
The downstream would be:
a leaf LDM node on a dedicated Linux server;
static IPv4;
TCP/388 connectivity available;
low bandwidth requirements;
no redistribution of the received feed.
The experiment will compare observation time, first local reception time,
delivery consistency, and propagation delay across different dissemination
paths, and evaluate whether earlier observations improve short-horizon
forecast updates.
If you are able to provide an upstream ALLOW, I would be very grateful to
hear from you.
If your organization does not provide external LDM downstream access
directly, I would also appreciate any recommendation for another LDM/IDD
operator or research-data provider that can provide this type of real-time
surface-observation feed.
I can provide the downstream hostname, static IPv4 address, LDM version,
and any other technical details privately if required.
Thank you for your time and consideration.
Best regards,
Toni Biston
