L1b sample products

Introduction

Below, sample L1b data products can be downloaded. These sample products were created using the 0.12.0 version of the TROPOMI L0-1b data processor. For L0 input, test data from the electrical functional model (EFM) of the instrument were used. These data contain noise and / or test patters. The sample products are provided as an example of the data format; they do not contain scientifically valid data. This means that these products can be used, for example, to test input routines, but not for testing L2 retrieval algorithms.

Sample products are provided for radiance and irradiance data for all 8 bands. For radiance data, the products are split by band. For irradiance data, the products are split by module, UVN (band 1 through 6) and SWIR (band 7 and 8). The data products contain a full orbit of data. The measurement scheme used for this orbit contains irradiance observervations near the northern terminator crossing. Orbits with irradiance observations, such as the provided sample orbit, contain less radiance measurements on the northern hemisphere than orbits without irradiance observations. Irradiance observations are normally performed once every fifteen orbits.

The format of the data products are described in the IODS, the metadata is described in the MDS and the L01b data processing algorithms are described in the ATBD.
