BOREAS FOLLOW-ON MOD-01 REGIONAL DAILY AVERAGED GRIDDED MET. DATA, 1994-1996
Get Data

Summary:

The regional data set provided by the HMet-02 Team and described in HMet-02 Area and Regional Hourly Gridded Met. Data, 1994-1996, on an hourly time step have been converted to averaged daily files by the MOD-01 group to reduce the size and number of files used for input to some of the carbon models.

Processing:

The regional data set provided by the HMet-02 Team and described in HMet-02 Area and Regional Hourly Gridded Met. Data, 1994-1996, on an hourly time step, have been converted to averaged daily files by the MOD-1 group to reduce the size and number of files used for input to some of the carbon models. Note that the daily data files contain floating point values rather than 16-bit integers. Below is a table that describes how the hourly Phase 3 meteorological variables were summarized to daily values. Note that some of the data files have been compressed using Zip compression.
 
Variable
Abbreviation		 Variable Name Units Method of Summary
Ta Air Temperature degrees C min/max/average
Td Dew Point Temperature degrees C average
Ud Wind Direction degrees from
true North		 average
U Wind Speed meters/sec average
Pres Air Pressure kPa average
Rsi Incoming Shortwave Radiation Watts/meter^2 average of values > 0
Lwi Incoming Longwave Radiation Watts/meter^2 average of values > 0
Precip Precipitation mm/day total

 

File Information:


The daily average gridded data for each variable for a year have been compressed in the following Zip files:

    ta_94_avg_day.zip    ta_95_avg_day.zip    ta_96_avg_day.zip

    ta_94_max_day.zip    ta_95_max_day.zip    ta_96_max_day.zip

    ta_94_min_day.zip    ta_95_min_day.zip    ta_96_min_day.zip

    ud_94_day.zip           ud_95_day.zip           ud_96_day.zip

    u_94_day.zip             u_95_day.zip              u_96_day.zip

    pres_94_day.zip       pres_95_day.zip         pres_96_day.zip

    rsi_94_day.zip          rsi_95_day.zip             rsi_96_day.zip

    lwi_94_day.zip         lwi_95_day.zip            lwi_96_day.zip

    precip_94_day.zip   precip_95_day.zip      precip_96_day.zip
 

Each Zip archive file contains 365(6) daily averaged gridded files.  Each file name has the following structure:

      yy-mm-dd_VariableAbbreviation_day.bin

where yy is the two-digit year, mm is the 2-digit month, dd is the 2-digit day, and VariableAbbreviation is the variable as listed in the preceding table.  Day is the averaging period.  Note the avg, max, and min variations for Air Temperature.

The data are stored as 4-byte binary float images, one image per day per variable (the data may need to be byte swapped to display correctly). The regional grid is 66 columns by 60 rows.
