Special Issue Information

Dear Colleagues,

Since the majority of the Earth’s surface is covered by water (oceans and inland waters) as well as mountains, deserts, and polar ice, meteorological observations are very limited and mostly come from buoys, island stations, ships, in situ sensors equipped on airplanes and aircraft dropsondes. Even for areas where traditional observations are relatively dense, it is difficult to meet the spatial and temporal requirements of mesoscale weather forecasts. In addition, the common ground-based observation system does not measure the important atmospheric composition information, e.g., ozone, dust, methane, sulfur dioxide, and carbon monoxide.

The modern growing constellation of polar and geostationary satellites orbiting the Earth provides continuous spectral observations of the global atmosphere and oceans at various spatial and temporal scales. Satellite data can help improve regional and global numerical weather forecasts via the data assimilation of radiance in numerical weather prediction models. The satellite radiation measurements on the different spectral regions can also be used to derive atmospheric state/compositions at different heights that are essential for the observation of the Earth’s systems at the microscale, mesoscale, synoptic, and global scales.

Improving the usage of satellite observations is highly important, since they contain valuable information to satisfy present and future observational needs and are critical for enabling applications with significant societal, economic and scientific benefits. Meanwhile, the quick development of information technology, e.g., artificial intelligence and machine learning (AI/ML), also provides the opportunity to handle the large size of the satellite data efficiently and leads to a growth of scientific usage of the satellite data observations.    

The aim of this Special Issue is to investigate the techniques for improving the uses of the satellite observations across the different portions of the electromagnetic spectrum (microwave, infrared, visible, etc.) onboard both operational and experimental environmental satellites, including but not limited to the satellites from international agencies, e.g., NOAA, NASA, EUMETSAT, ESA, CMA, JMA, et al., and commercial satellite data.

In particular, but not exclusively, we encourage manuscripts that address the uses of satellite data to observe the atmospheric state and composition, severe weather events, weather and climate studies, and numerical weather forecasts.

Observation bias and error characteristics are the preconditions for the effective assimilation of observation data. In this paper, the bias and error characteristics of the AHI (Advanced Himawari Imager (AHI) and AGRI (Multi-Channel Advanced Geostationary Orbit Radiation Imager (AGRI) data are compared and analyzed, with an emphasis on the observations obtained from land areas. The results show that the observation errors of the two instruments for the ocean area have a good channel consistency over ocean areas, which are all with errors of about 0.6 K; however, the bias and error are significantly affected by the land-surface types and terrain heights over land. For most of the AHI channels, the bias in urban-area bias is smaller than that of those of other surface types, while that of the AGRI data exhibits just the opposite trend, with obviously larger biases in urban areas. However, the observation errors of these two instruments in urban areas are significantly smaller than those of other surface types. The biases of the two instruments do not extensively change much with the terrain height, only slightly decreasing when the height is above 1000 m; however, the observation errors increase obviously with the increase of terrain heights. The difference between the two instruments is that the observation error of the AHI data tends to be stable and stabilizes above 1000 m, while that of the AGRI data is relatively stable below 500 m. The observation errors of the CO2-sensitive channels of the two instruments over the land areas are obviously smaller than those of other near-surface channels, which may indicate that the data obtained in these two CO2 channels have good application prospects for assimilation over land.
