Of the order of 20 to 100 co-locations have been identified at about 20 Brewer and Dobson sites and at 11 SAOZ sites, sampling many latitudes from the Arctic to the Antarctic. The following preliminary conclusions could be drawn:<br />Short scale temporal variations in the ozone column as captured by ground-based instruments are reproduced very similarly by S5P. This overall good agreement is corroborated by Pearson correlation coefficients well above 0.9.The bias between S5P and reference data at individual stations rarely exceeds 3%,and the network-averaged bias is about +1%.The 1-sigma spread of the differences (between S5P and reference data) rarely exceeds 3-4% for the comparisons with direct-sun instruments.The analysis of potential dependence of the S5P bias and spread on key influence quantities, namely, the Solar Zenith Angle (SZA), Air Mass Factor (AMF) and cloud fraction of the S5P measurement, does not reveal any variation of the bias larger than 2% over the range of those influence quantities. The spread of the differences increases up to 7% with increasing SZA.Overall, the quality of the initial L2_O3 PDGS NRTI v1.0.0 data product appears to comply with the S5P mission requirements. Some patterns in S5P vs. GOME-2/MetOp-A comparison maps, seemingly related to cloud cover, require further investigation.<br />For details, please read the report in pdf format.</description><link>http://s5p-mpc-vdaf.aeronomie.be/?option&#61;com_vdaf&amp;view&#61;showReport&amp;format&#61;rawhtml&amp;id&#61;28</link><guid isPermaLink="false">28</guid><pubDate>2018-07-27</pubDate><enclosure url='http://s5p-mpc-vdaf-dev.aeronomie.be//UploadDir/reports//pdf/S5P-MPC-VDAF-WVA-L2_O3_20180720.pdf' length='536060' type='application/pdf' /></item><item><title>Preliminary comparison of TROPOMI/S5p RPRO CLOUD CAL cloud top height and CRB cloud height against ground-based CLOUDNET data.</title><description>From the Sentinel-5p TROPOMI L2_CLOUD RPRO 1.0.0 data, (November 2017 - begin May 2018), the ROCINN-CAL cloud top height and ROCINN-CRB cloud height were compared with the ground-based cloud target classification measurements from the CLOUDNET database (http://www.cloud-net.org/), obtained within the same time period. Clear correlations are established. The CAL cloud top height is lower than the CLOUDNET height by ~0.5-1 km and the CRB cloud height is lower than the CLOUDNET mid-height by 0.3-0.5 km.</description><link>http://s5p-mpc-vdaf.aeronomie.be/?option&#61;com_vdaf&amp;view&#61;showReport&amp;format&#61;rawhtml&amp;id&#61;27</link><guid isPermaLink="false">27</guid><pubDate>2018-07-25</pubDate><enclosure url='http://s5p-mpc-vdaf-dev.aeronomie.be//UploadDir/reports//pdf/S5P-MPC-VDAF-WVA-L2_CLOUD_20180720.pdf' length='1549219' type='application/pdf' /></item><item><title>First comparison results for the S5P CO product based on correlative reference measurements acquired by FTIR instruments contributing to NDACC and TCCON networks.</title><description>This VDAF web article gives further details on the first comparison results presented in the CO product readme file for the CO data product release. The main conclusion is that the product quality of this initial L2 CO dataset complies with the S5P mission requirements.<br />Current conclusions are however based on a limited initial dataset of measurements between November 2017 and 1 May 2018. The current validation analysis need to be extended over a full year of measurements, hence, a full cycle of key influence quantities, in order to enable detection of potential patterns, dependences, seasonal cycles and longer term features like drifts.</description><link>http://s5p-mpc-vdaf.aeronomie.be/?option&#61;com_vdaf&amp;view&#61;showReport&amp;format&#61;rawhtml&amp;id&#61;26</link><guid isPermaLink="false">26</guid><pubDate>2018-07-19</pubDate><enclosure url='http://s5p-mpc-vdaf-dev.aeronomie.be//UploadDir/reports//pdf/S5P-MPC-VDAF-WVA-L2_CO_20180716.pdf' length='620670' type='application/pdf' /></item></channel></rss>
