Drop in aircraft observations could have impact on weather forecasts
One aspect of the COVID-19 pandemic has been a reduction in aircraft flights
and thus of the aircraft-based observations available to weather prediction centres.
The observations are used together with many others
to help estimate the state of the Earth system at the start of forecasts.
For daily air traffic reduction over Europe
From the other hand, private flights have seen a significant rise in demand
for group evacuations from affected areas
and from passengers who are looking to protect themselves and their families.
In addition the spatial distribution of observations made by aircrafts used by the ECMWF model, run by run:
Other observation types can be selected including SYNOP weather stations, ships, buoys, all observations made by satellites...
Can we find the pro-covid AMDAR observations?
Here are archives of observations, but those are monthly averages. Waiting for March results, it will possible to make comparison with pro-covid averages?
But I didn’t look in detail. May you find what you need.
Here's my contribution from ~2500 this morning: it's rough as hell today! What kinda Jack wagon goes up in weather like this anyways? Wind shear, near imc at times and freaking cold over 1k. Oughta get grounded I should... lol
thanks my issue has been fixed.
