+==== compareTropomi ====
+  * Functions: ''compareTropomi''
+  * Description: Compares the hourly average 1.5 level ozone product for a given brewer with the [[https://www.tropomi.eu/data-products/ozone-total-column|Total ozone column TROPOMI L2 OFFL product]].
+  * Example: [[http://eubrewnet.aemet.es/eubrewnet/data/get/compareTropomi?brewerid=186&stationid=42&date=2022-01-01&enddate=2022-01-31&format=text]]
+  * Input:
+      - ''brewerid'': see [[codes:dbaccess#common_inputs|Brewerid in common inputs]]
+      - ''stationid'': Eubrewnet station id. If ''stationid'' is not provided, the station where the Brewer is located in ''date'' is used to select the ERA5 data.
+      - ''date'': see [[codes:dbaccess#common_inputs|Date in common inputs]]
+      - ''enddate'': see [[codes:dbaccess#common_inputs|Enddate in common inputs]]
+      - ''format'': see [[codes:dbaccess#format|Format]]
+      - ''debug'': In the output, individual measurements are returned instead of hourly averages.
+      - ''v2'': The comparison is made using the ozone product level 1.5 version 2 for the Brewer.
+  * Output:
+      - ''gmt'': UTC time.
+      - ''o3_avg'': Mean hourly ozone L1.5 for brewerid.
+      - ''o3_tropomi'' Total ozone column L2 OFFL product for the station at which the brewer was at ''date''.
+      - ''diff'': difference between o3_avg and o3_era5 in Dobson units.
+      - ''reldiff'': relative difference between o3_avg and o3_era5 in %
