The amount of data from aircraft has also increased in recent months as air travel has picked up, the agency said.

In the early stages of the Coronavirus pandemic, organizations such as NASA pointed out satellite readings showing that strict lockdown restrictions seemed to be having a positive effect on the environment by reducing air pollution. Those other sources include satellites, ocean buoys and instruments carried aloft by weather balloons. With the various weather forecasting centres across the world producing their own weather models, comparing them is a key tool for a forecaster looking to create an accurate forecast. Weathermodels.com: Beautiful & affordable weather forecasting tools for professional and enthusiasts.
Currently about 40 airlines participate in the program, and in all about 3,500 aircraft have the equipment to make and transmit observations.
Slump in Air Travel Hindered Weather Forecasting, Study Shows.
The sharp decline in air traffic has affected the quality of weather forecasting models. “But it’s not quite that much.” They found that eliminating 80 percent of the data produced errors that were 30 to 60 percent of the errors that would have resulted from having no data at all. This tool enables you to do just that at a glance, just click the times below to view the outputs from the UK Metoffice, ECMWF, NOAA (GFS and Global Ensemble) alongside eachother.
Government researchers have confirmed that the steep decline in air traffic during the coronavirus pandemic has affected the quality of weather forecasting models by sharply reducing the amount of atmospheric data routinely collected by commercial airliners. As air traffic declined by about 75 percent or more worldwide near the beginning of the pandemic, the number of observations and data points dropped by roughly the same amount the researchers explain. During the first months of the pandemic, when air traffic declined by 75 percent or more worldwide, the number of observations dropped by about the same percentage. In their paper, the researchers showed that short-term forecasting models have a demonstrably worse forecast skill when they receive less data on temperature, wind, and humidity from aircraft. This data is then are transmitted in real-time to forecasting organizations around the world, including the National Weather Service in the U.S.
“We had to look to see if 80 percent gives 80 percent of impact,” Dr. Benjamin said. COVID-19 Has Affected Weather Forecasting, Study Says.
They are transmitted in real time to forecasting organizations around the world, including the National Weather Service. The observations are made by instruments aboard thousands of airliners, mostly based in North America and Europe, as part of a program in place for decades.
The researchers and others had suspected this would be the case because atmospheric observations from passenger and cargo flights are among the most important data used in forecasting models. “With every kind of observation that goes into weather models, we know they have some impact on improving accuracy overall,” said one of the researchers, Stan Benjamin, a senior scientist at the Global Systems Laboratory, a part of the National Oceanic and Atmospheric Administration, in Boulder, Colo. “If you’ve really lost a lot of observations of some kind there could be some stepping back in skill overall.”. A decline in air traffic during the coronavirus pandemic sharply reduced the amount of data routinely collected by commercial airliners. Animate, compare, export and create customised GIFs. With the various weather forecasting centres across the world producing their own weather models, comparing them is a key tool for a forecaster looking to create an accurate forecast. Adam Gray/Barcroft Media, via Getty Images. The daily number of flights by passenger aircraft in the United States is now at about 50 percent of pre-pandemic levels. the sharp decline in air traffic during the coronavirus pandemic has greatly reduced the amount of atmospheric data collected by commercial airliners, a new. Dr. Benjamin, along with two colleagues working at the laboratory, Eric P. James of the University of Colorado and Brian D. Jamison of Colorado State University, simulated conditions during the pandemic in April by taking data from 2018 and 2019 and eliminating 80 percent of it before feeding it into a forecasting model developed by NOAA called Rapid Refresh. Weather forecasting includes predictions of both atmospheric phenomena and changes …
Weather forecasting is notoriously difficult, but in recent years experts have suggested that machine learning could better help sort the sunshine from the sleet.

The data collected can be from deep space satellites (e.g., NOAA’s Deep Space Climate Observatory (DSCOVR)), weather balloons, radar systems, nowcasting weather warnings and environmental analytics and sometimes from IoT based sensors. Now, it turns out that a different method for taking readings of the environment has been adversely affected by the pandemic: the sharp decline in air traffic during the coronavirus pandemic has greatly reduced the amount of atmospheric data collected by commercial airliners, a new study explains. They are the mathematical basis of all computer models for weather forecasting.
While fewer data leading to worse forecasts is hardly a surprising finding, the research is notable for highlighting the hidden role that the aviation industry plays in weather forecasts — an effect that has been hindered by the ongoing pandemic.
As The New York Times explains, observations are made by instruments aboard thousands of airliners, mostly flying over North America and Europe, as part of a program that has been in place for decades. The study, which was published in the Journal of Applied Meteorology and Climatology, shows the specific impact of the reduction in data in numbers. 1-hourly data and 6z/18z extra runs), EPS, EPS 46-days, UKMET, GEFS, GFS, HRRR, CMC, CAMS and many more here.

While the researchers showed that the data loss contributed to making the model less accurate, NOAA said that so far it had not seen an impact on the type of short-term forecasts that companies use to make business decisions or a person might use to decide if they need to take an umbrella when going out.
According to The New York Times, the National Oceanic and Atmospheric Administration (NOAA) has countered by saying that the reduction in data has so far had almost no real-world impact and that air traffic is slowly increasing once again. In the United States, Delta, United, American and Southwest and the cargo carriers United Parcel Service and FedEx are involved. Models. Well, the traditional models of weather forecasting are based on statistical measures of numeric models, and it does not give answers in binary.
The sharp decline in air traffic has affected the quality of weather forecasting models.

Air traffic declined by 75 percent or more in the first months of the pandemic.

Weather forecasting, the prediction of the weather through application of the principles of physics, supplemented by a variety of statistical and empirical techniques. “We are not directly seeing a readily apparent reduction in forecast accuracy as we continue to receive valuable data from passenger and cargo aircraft along with numerous other data sources,” an agency statement said. The agreement with the International Air Transport Association calls for adding more airlines and aircraft to the program, including those that have routes in Africa and other less-monitored areas.

They compared the errors that resulted to those if the model included no aircraft data. Specifically, it says that eliminating 80 percent of the data produced errors that were equivalent to 30 to 60 percent of the errors that would have been made with no data at all.
...Or you can join the friendly and lively. Flights by cargo aircraft were not as affected.
They have not changed over the past 50 years, but many other things have changed. image/svg+xml. Separately, the World Meteorological Organization, which in the spring had expressed concern about the loss of aircraft-based observational data, announced this week that it had signed an agreement with an aviation industry group to expand the observation program to cover parts of the world where little data is currently gathered.
This allows for situations where a single model, forecasting a large, land-falling hurricane for example, can be discarded when the vast majority of models are forecasting a swift turn out to sea.
In a study, researchers showed that when a short-term forecasting model received less data on temperature, wind and humidity from aircraft, the forecast skill (the difference between predicted meteorological conditions and what actually occurred) was worse.
