Each page shows how to do one thing. If you are new to uataq, start with
:doc:`/getting_started/first_data`.

- :doc:`find_sites_and_data`: which sites measure a pollutant, when they have
  data, and how recent it is
- :doc:`read_data`: several pollutants and sites in one table, everything an
  instrument logged, and reads of a year or more
- :doc:`data_levels_and_flags`: what each data level holds, what ``final``
  keeps, and the flags
- :doc:`mobile_sites`: the TRAX trains and the buses, where each measurement
  was, and their two clocks
- :doc:`errors`: what an error or an empty result means, and what to do
