Summary
These datasets consist of Automated Weather Station observations
from seven sites involved with the Anglo-Brazilian Amazonian Climate
Observation Study. Items measured were temperature, humidity,
rainfall and radiation balance.

Datasets are presented in 6 month blocks in the following format.

AB-C[sitecode].[year][A or B]

A and B ... correspond the first and second half of the year.

Site Codes:

FD Fazenda Dimona Manaus (ab-cfd.exe)
NS Fazenda Nossa Senhora Aparecida Ji-Parana (ab-cns.exe)
BS Fazenda Boa Sorte Maraba (ab-cbs.exe)
RD Reserva Ducke Manaus (ab-crd.exe)
RJ Reserva Jaru Ji-Parana (ab-crj.exe)
RV Reserva Vale do Rio Doce Maraba (ab-crv.exe)
MS Urban climate Manaus (ab-cms.exe)

Each line of the files contains the following data

Quality
Particular problems were experienced with the rain gauges which lead
to a poor record of rainfall at some of the sites. Periods of longer
than 24 hours for which there is no rainfall record are listed.
