Radiance comparison of IASI and AVHRR on MetOp-A

摘要

Accurate and precise satellite radiance measurements are important for data assimilations in numerical weather prediction models and climate change detection.Given the high-resolution spectral IASImeasurements with high data quality,it allows us to assess the radiance measurements of heritage instuments that share the same spectral region with IASI.Intheis are convolved with the AVHRR SRFs to observations.The LASI spectral radiances are convolved with the AVHRR pixels instde each LASI.
