Climate Data Records (CDR) provide dozens of variables. Use the information below to help find what you’re looking for. Click through to the product pages for access to the data. Data is available online, some are supported via THREDDS and AIRS. Most are also available via the Cloud (e.g. AWS, Google).
- Upper tropospheric water vapor from IR Sounder Upper Tropospheric Humidity BT CDR
- Total precipitable water from Hydrological Properties CDR
PATMOS-x Cloud Properties, Cloud Properties - ISCCP H-Series and Polar Pathfinder - Extended provide several cloud parameters (cloud fraction, pressure, optical depth, etc.) The Hydrological Properties bundle only provides cloud, liquid, water path and ice water path.
| CDR | Period of Record | Spatial Coverage | Spatial Resolution | Temporal |
|---|---|---|---|---|
| AVHRR Cloud Properties - NASA CDR | 1978–2016 | Global | 4 km | twice daily |
| PATMOS-x Cloud Properties | 1981–present | Global | 0.1 deg | twice daily |
| Polar Pathfinder -Extended | 1982–present | Poles (EASE grid) | 25 km | twice daily |
| Cloud Properties - ISCCP H-Series | 1983–present | Global | 1 deg | 3 hourly |
| Hydrological Properties | 2000–present | Global | ~16 km swath | twice daily |
All data are global gridded at 2.5 deg. equal angle.
| CDR | Period of Record | Layers |
|---|---|---|
| Mean Layer Temperature - NOAA CDR | 1978–present | TMT, TUT, TLS |
| Mean Layer Temperature - RSS | 1978–2023 | TLT, TMT, TLS, TTS |
| Mean Layer Temperature - UAH | 1978–2023 | TLT, TMT, TLS, TTS |
| Mean Layer Temperature - UCAR (Lower Stratosphere) | 1986–2019 | TTS, TLS |
| Mean Layer Temperature - UCAR (Upper Troposphere and Lower Stratosphere) CDR | 1986-2019 | TTS |
- Ocean Near-Surface Atmospheric Properties CDR - Provides air temperature, wind speed, and specific humidity above the ocean surface
We have several CDRs related to precipitation. Each has its own unique strengths.
| CDR | Period of Record | Spatial Coverage | Spatial Resolution | Temporal |
|---|---|---|---|---|
| Precipitation - GPCP Monthly CDR | 1979–present | Global | gridded @ 2.5 deg | Monthly |
| Precipitation - PERSIANN CDR | 1983–present | 60N - 60S | gridded @ 0.25 deg | Daily |
| Precipitation - GPCP Daily CDR | 1996–present | Global | gridded @ 1 deg | Daily |
| Precipitation - CMORPH CDR | 1998–present | Global | gridded @ 0.25 deg | Daily |
| Hydrological Properties CDR* | 2000–present | Global | Satellite swath (~16 km) | Daily |
* Hydrological properties provide an instantaneous rain rate, not accumulated precipitation.
- Ocean Heat Fluxes CDR (Latent and Sensible Heat Fluxes over the oceans)
- Polar Pathfinder - Extended CDR (surface radiative flux, TOA radiative flux)
- Snow Cover Extent (Northern Hemisphere) CDR
- Snow cover and snow water equivalent (from the Hydrological Properties CDR)
- Polar Pathfinder - Extended CDR - This CDR provides several ocean-realated data for polar regions such as:
- Sea ice thickness
- Surface Albedo
- Surface Temperature
| CDR | Period of record | Spatial coverage | Spatial Resolution | Temporal |
|---|---|---|---|---|
| Sea Surface Temperature - Optimum Interpolation CDR | 1981–present | Global | 0.25 deg, 1440x720 grid | Daily |
| Sea Surface Temperature - Pathfinder CDR | 1981–2014 | Global | 4.6 km satellite swaths | twice daily |
| Polar Pathfinder - Extended CDR | 1982–present | Polar | 25 km EASE grid | twice daily |
| Sea Surface Temperature - WHOI CDR | 1988–2021 | Global | 0.25 deg, 1440x720 grid | 3 hourly |
