Reproducible code for generating the results in Sections 2 and 3 of the article `On statistical approaches to generate Level 3 products from remote sensing retrievals' by Zammit-Mangion, A., Cressie, N., and Shumack, C.
Figure 8 (e): The difference between the FRK Version 8r predictions and those of FRK Version 7r for 13 May 2016.
For reproducing the results in Section 2 please run the R
script Section2_Running_example.R
.
For reproducing the Level 3 products and the results in Section 3 you will need to run the scripts in the three folders.
1_Generate_FRK_L3: Scripts in this folder download the V7 and V8 data, generate the Level 3 products, and filter the product at the TCCON locations for comparison later.
2_Filter_TCCON: Scripts in this folder download the TCCON data and subset them according the overpass time of OCO-2.
3_Analyse_Results: Scripts in this folder are used to generate the comparison tables and figures in Section 3.
The FRK products can be downloaded directly from here.
A pre-print version of the paper will be available shortly.
