Table 1: Explanation and Values for Mandatory and Optional Web Service Parameters
| Mandatory Parameters | Explanation | Values |
|---|---|---|
| year,month,day | Starting time moment (year= 1992 to present), (month=1 to 12), (day = 1 to max num, depends on month) |
Year: 1993 to present (must be 4-digits) Month: 1 to 12 Day: 1 to max_day_of_month |
| AVG | Data Format | All points: AVG=10 Daily average: AVG=20 |
| [data_type] | Data Types (See Table 2) | [data_type]=1 |
| Optional Parameters | ||
| year2,month2,day2 | Ending time moment** | Year: 1993 to present (must be 4-digits) Month: 1 to 12 Day: 1 to max_day_of_month **if year2,month2, and day2 are omitted, then the current day is assumed |
| hour, hour2 | Specified beginning (hour) and ending hour (hour2) | Hour: 0 to 23 if not specified, then the hour is set to zero; time2 is incremented to next day and hour2=0 |
| site | AERONET site name |
Exact match of AERONET database name If none specified, then all sites are searched for data during the time interval specified |
| lat1,lon1,lat2,lon2 | Bounding Box ** | lat1,lon1 - Lower Left **values must be in decimal degrees (including the decimal) |
| lunar_merge | Enable Lunar AOD (Provisional) Only Download | 0 - No Lunar |
