This is a convenient scheme for making direct surface measurements.

The height of the cloud base can be estimated from surface measurements of air temperature and humidity.

For comparison, the surface measurements made with identical instrumentation is shown in yellow.

Information about quantities at the lateral boundaries can be taken into account as surface measurements and upper air soundings.

Sets of surface measurements are important data to meteorologists.

In the 1970s, buoys were introduced to improve the resolution of surface measurements, which until that point, were not available at all over sea surfaces.

"Table of Measures": conversion tables for grain, weights and surface measurements.

There must be some oxides for which that technique is not a surface measurement but a solid/solution measurement.

Contrary to climate models and surface measurements, their results showed a cooling in the troposphere.

A marine navigation radar may also be a tool for surface current measurements.
