(2) Surface Radiation Monitoring system:
      Broadband instruments: CM21, CG4, NIP-CH1
      MFR-7 / UV-MFR-7
(3) Surface fluxes monitoring system:
      Eddy covariance system: CSAT3, LI7500
      Large Aperture Scintillometer (LAS)
(4) Soil and vegetation parameters monitoring system :
      Soil heat fluxes, temperature and moisture measurements: HFP01SC-L, STP01-L, CS616-L
      Soil chemical, physical and biological parameters measurement: MALVERN, LI-COR 64009
(5) Ambient Air Quality Monitoring System:
      ML9830B, ML9810B, ML9850B
      ML9841B, RP1400a, TNMH 462

(6) Aerosol optical properties monitoring system:

(8) Sky Conditions Measurements:
      Model 880
(9) FY & EOS/MODIS Data Digital Video Broadcasting System:
      FY-1D/CHRPT
      NOAA-16,17,18/HRPT
      EOS/TERRA&AQUA /MODIS

(10) GPS reception system.

SACOL is a participating site in the Coordinated Enhanced Observing Period (CEOP) which was initiated as a major step towards bringing together the research activities in GHP/GEWEX and related projects in WCRP (CLIVAR; CLiC). CEOP has now developed into an important element of WCRP. It has also been endorsed by the Integrated Global Observing Strategy Partnership (IGOS-P) as the first element of the IGOS-P Integrated Global Water Cycle Observations (IGWCO) Theme. An AERONET-Cimel sun photometer for spectral, radiative, and aerosol optical properties (Holben et al., 1998) has been measured and archived at SACOL. The Micro-Pulse Lidar Network (MPLnet) lidar (Welton et al., 2001) is also operational at SACOL. It provides real-time images of the vertical profile of backscatter. Many additional measurements made at SACOL are shown in Table 1.
