wp_objectives:
The objective of this WP is the continuous development and improvement of the operational HCHO product.

wp_methodology:
DOAS algorithm
- (BIRA) Investigation of correction methods for time-dependent (and along orbit) slit function changes
- (BIRA) Investigation of added-value of earthshine mean radiance spectra as DOAS reference instead of the SMR
- (BIRA) Optimisation of retrieval settings to Metop-C

AMF/VCD calculation
- (BIRA) Implementation of improved surface albedo climatology for AMF calculation
- (DLR) Improved treatment of clouds and aerosols    
         AMF calculations using Cloud as Layers (CAL)  
- (DLR) Improved error estimates
- (DLR) Algorithm adaptation to Metop-C
