SESSION: Assimilation & Re-analysis in NWP & AC/AQ Models

The introductory talks (and discussions) will cover:

1. Incoming and TOA UV-VIS-SWIR data assimilation ecosystem

NWP data assimilation overview, latest advances, plans and challenges by 2030 and beyond
AC/AQ model data assimilation overview, latest advances, plans and challenges by 2030 and beyond

2. Key issues which could be addressed by improved radiometric uncertainty in UV-VIS-SWIR

The objectives of facilitated discussions are:

1. Identify the role of TRUTHS as direct input or indirect as an anchor to monitor/calibrate other missions’ products

2. Specify the required TRUTHS products (L1, 2 & 3), including data access, content and timeliness including considerations of the spatial, spectral and temporal resolution/averaging and required metadata, etc., for:

a. Incoming SSI/TSI at TOA

b. TOA spectral radiance & reflectance (and surface reflectance if applicable)
