NR01
4 component net-radiation sensor
NR01 is a 4-component net-radiation
sensor that is used for scientific-grade energy balance studies. The instrument
has separate measurements of solar (Short Wave or SW) and Far Infra-Red (Long
Wave or LW) radiation. Major improvements relative to comparable instruments
include weight (reduced), solar offsets in the LW signal (reduced), ease of
leveling (high, because levelling assembly is included).

INTRODUCTION
NR01 serves to measure the 4 separate
components of the surface radiation balance. Working completely passive, using a
thermopile sensors, NR01 generates 4 small output voltage proportional to the
incoming and outgoing SW and LW fluxes. The SW solar radiation sensors are also
called pyranometers, the LW sensors are also called pyrgeometers. For
calculation of sky- and surface temperature, a Pt100 temperature sensor is
included in the pyrgeometers.
In order to avoid deposition of dew, the
pyrgeometers may be heated. A 2-axis levelling assembly is included.
The NR01 cable
can easily be installed or replaced by the user. See also
RA01 radiameter on the next page, which is a single side version of NR01.
Combined with estimates of SW albedo- and of surface temperature, this
instrument can also be used for estimation of net-radiation. For a single
pyrgeometer see also IR02.
