SIGEO-CTFS meteorological monitoring METADATAThe SIGEO-CTFS stations comprise several sensors recorded automatically by a CR1000 datalogger (Campbell Scientific) at 5 min time interval. These sensors include:Aspirated and shield temperature and relative humidity sensor plus an additional secondary temperature sensor (MetOne Instruments) 2-D sonic anemometer WS425 (Vaisala)Tipping rain bucket TB4-L (Campbell Scientific)Solar radiometer CMP11 (Kipp&Zonen), plus a secondary radiometer LI-290 (LiCOR biogeoscience)Data are available in comma separated format after passing a supervised QA/QC. We produce a new file for each year and each station with name XXX_metdata_5min_yyyy.csv, where XXX is a three code site identificator and yyyy is the year.

Four standardized stations were built in collaboration with Bill Munger (Harvard University) and installed closed to four CTFS plots: SCBI, KHC, HKK and BCI. The SIGEO-CTFS stations comprise several sensors recorded automatically by a CR1000 datalogger (Campbell Scientific) at 5 min time interval. These sensors include:Aspirated and shield temperature and relative humidity sensor plus an additional secondary temperature sensor (MetOne Instruments) 2-D sonic anemometer WS425 (Vaisala)Tipping rain bucket TB4-L (Campbell Scientific)Solar radiometer CMP11 (Kipp&Zonen), plus a secondary radiometer LI-290 (LiCOR biogeoscience)We recognize that meteorological data are crucial information to understand how forest ecosystems work and how they respond to a changing environment. The data are intended to be freely accessible to all the CTFS community trought the CTFS website and constitutes a first step toward a wider meteorological program that will involve potentially all the network of sites. Metadata and other information are available here. ................
