I. Overall climate information services
- Climate information (data and products) provided operationally for the general public and/or for specific information users
- Long-range forecasts
- Climate monitoring
- Analysis and assessments based on historical data
- Historical climate data
- Climate change projections
- Long-term trends
- Others
- Drought outlook and early warning
- Seasonal forecast over ECO region
- National meteorological application services to support end users (in Persian TAHAK program) which is newly initiated by IRIMO
- URL of a portal website providing climate data/products
II. Long-range forecast
- Long-range forecast services
-
Monthly predictions - 2 to 6 weeks
Sub-seasonal predictions - 6 weeks to 2 months
Seasonal predictions - 3 to 6 months
Future climate projection under IPCC emission scenarios
- Methods taken by NMHS to generate long-range forecast products
- We get Grid Point Value(GPV) data from NOAA, Tokyo climate center and Seoul WMO lead center. Then some statistical calibration methods such as ANN, MA and regression method will be done over GPVs to improve the seasonal forecast accuracy Iran. ECMWF's ERA-Interim gridded data was used to calibrate the model forecasts. English abstract of method used is available in the bellow link:

- Use of climate products provided by other NMHSs or meteorological institutes for long-range forecast
- https://climate.copernicus.eu/
- JMA/MRI-CGCM, NOAA/CFS v.2, ECHAM, GFDL, NCAR CCSM, KMA, ECMWF
- Plan to provide long-range forecasting services in the future
- Running dynamical seasonal forecast models
III. Climate Monitoring
- Regular climate monitoring reports
-
Monitoring of climate extremes (including drought monitoring and climate watch)
- http://www.cri.ac.ir/ (Persian)
- http://ndwmc.irimo.ir/far/ (Persian)
IV. Climate Data Services
- Historical climate data provided through the Internet
- Partly available http://irimo.ir/eng/wd/720-Products-Services.html (Persian)
- Digitization of historical climate data
- Yes
- Provision of climate data through the website with limited/unlimited access
- Some climate data are accessible to registered users under password protection free of charge. Access to daily and sub-daily data are limited. For university student, some of data are free of charge.
V. Regional Cooperation for the improvement of climate information services
- Name(s) of Regional Climate Outlook Forums (RCOFs) in which the NMHS participates
- ECO Regional Center for Risk Management of Natural Disasters (ECO-RCRM)
Three regional workshops were held in I.R. of Iran National Center for Climatology in Mashad by joining 10 countries in the west and Central Asia including Turkey. - FOCRAII
- ECO Regional Center for Risk Management of Natural Disasters (ECO-RCRM)
- Provision of relevant information based on the consensus forecast at RCOF(s) to domestic users
- Seasonal forecasts are prepared by national climate center by getting data from TCC, NOAA, ECMWF, and Seoul WMO-LC-LRF

VII. Case study/Best practices in the application of climate information
(1) The followings were presented at the first meeting of the Intergovernmental Board on Climate Services (Geneva, July 2013).
| Title | Abstract | Poster |
|---|---|---|
| Seasonal Forecast over Khorasan-Razavi Province, Iran using Statistical Post processing MRI-CGCM3 Output |  |
----- |
| A Drought Early warning and Outlook system over I. R. of Iran (DOES) | |
|
| Climate Change Projection over Iran using the PRECIS Regional Modeling System | |
|
| Assessment of Agro-climatic Indices over North-east of Iran under Climate Change Scenarios | |

(2) IRIMO has implemented a system called TAHAK (applied meteorological development) to provide practical data and information for agricultural users. This information includes agro meteorological newsletters, recommendations, warnings and other useful information to meet our national agro meteorological requirements.
